Over the course of the last few weeks, we've seen Peter grapple with difficult personal decisions and put his heart on the line in the name of finding love. All these ups and downs culminate in one of the biggest moments of Peter’s life: the final Rose Ceremony and proposal. Will he get down on one knee and ask Hannah Ann or Madison to be his forever? Will he even propose?

Monday, March 9, marks the beginning of the end of Peter’s journey as the Bachelor. In honor of the Season 24 finale, here's a look back at some of the biggest moments from this season of "The Bachelor."

Hannah Brown shook things up when she arrived at Bachelor Mansion that first night, much to Peter’s surprise. She handed him back the wings he gifted her when she stood at the end of the driveway on her season. Hannah told Peter, "When I heard you were going to be the Bachelor, I had mixed emotions. But when I stood where you are, you said you wanted to find your co-pilot and you gave me something. I want you to find that person, so I brought these back for you."

Peter thanked her for the generous gift, but that wasn’t her last cameo on the show. Hannah hosted a group date, which led to the two of them having an emotional and intense conversation backstage about their relationship and how she sent him home in Greece. He ultimately asked her if she wanted to "come be part of the house," but she turned down the opportunity.

A champagne bottle transformed from sentimental gift to a source of tension, and that drama bubbled over from one week to the next. Kelsey brought a bottle of bubbly to the show to share it with Peter, but a case of mistaken identity caused Hannah Ann to open Kelsey’s bottle instead.

The mistake and its ensuing drama became known as Champagnegate, and it was the cork pop heard 'round the world. The hostilities came to a head when Hannah Ann and Kelsey discussed what happened, and Hannah Ann said "finasco" instead of "fiasco."

New controversies about Alayah quickly overshadowed the Champagnegate scandal. Some women addressed their concerns about the former Miss Texas USA to Peter, deeming her "fake" and "manipulative." Peter took their apprehensions about Alayah to heart, and he sent her home, only to immediately question his decision.

Alayah returned a week later in Cleveland and shocked all the women. Peter handed her the group date rose despite the fact she did not attend the actual date, and this left the women irate. Peter sat Alayah and Victoria P. down together and demanded clarification about their relationship with each other prior to the show.

The rest of the women called Peter out during the Rose Ceremony cocktail party, and Peter told Alayah it would be easier if she left.

Is running into your ex while on a date with your new boyfriend the best or the worst thing to happen? For Victoria F., it seemed like the latter.

Peter whisked Victoria off to Cedar Point amusement park near Cleveland for their first one-on-one date. After a day of riding on actual roller coasters, Victoria dealt with an emotional one when she saw her ex Chase Rice singing onstage during her date’s private concert.

The Bachelor had no idea about their past until later that night, when Victoria tearfully revealed their previous relationship.

Peter suffered a rather gruesome injury in Costa Rica — thankfully not while on a date. The Bachelor hit his head on a golf cart while holding a glass, and the glass cut his forehead. The wound required stitches and left him with a large scar.

He initially told the women he "locked eyes" with a puma. "My animal instinct took over and I did what needed to be done," he said with an entirely straight face. He then admitted the true story, which resulted in lots of laughs and self-deprecating humor.

Moral of the story: Watch your head and hands when you’re near a golf cart!

Tammy and Mykenna’s beef caused them to receive a dreaded two-on-one date invite, which Peter used as time to understand their bad blood. Tammy told Peter she thought Mykenna wasn’t mature enough and that she believed Mykenna used her time on the show to "build her brand."

Mykenna offered her own two cents on the matter, but it proved to be a futile effort for both women. Peter sent Tammy home after their two-on-one and then Mykenna a few moments later at the Rose Ceremony.

Hometown Dates are a valued opportunity to understand someone’s backstory and family. Peter’s trip to Virginia Beach, Virginia, did not go as planned — at all. He and Victoria started off the day walking on the beach, getting ice cream, and taking photos together. Then, she surprised him with a Hunter Hayes concert in order to make up for the Chase Rice debacle.

But Peter’s ex Merissa took him aside and addressed some concerns about Victoria. "I know that you’re a great guy and I don’t think you deserve what you’re on a date with right now," she asserted. Merissa explained she and Victoria used to be friends, warning him, "There have been many relationships broken up because of her. I don’t think it’s a great relationship to be in."

After an emotional Hometown Date Rose Ceremony, Madison took Peter aside to tell him something important before heading into Fantasy Suite week. She said, "I want to be honest about who I am. Next week if you were to sleep with someone else, it would be really hard for me to move forward in this. I owe it to you to be up-front and honest with you about that."

The already tense Fantasy Suite week situation got escalated when the three remaining women had to share a hotel suite, which typically does not happen. Madison had the last date of the week, which only increased her anxieties about Peter and their future together.

Madison and Peter went on an adrenaline-filled day portion of their date in Gold Coast, Australia. It all took a turn, however, at night, when Madison confronted him about her personal “expectations” and "commitment" to herself. Peter explained, "The fact of the matter is, I have two other relationships right now."

Madison said, "I wouldn’t be able to say yes to an engagement if you have slept with the other women. I’m not trying to come across as judgmental or hold something over your head, but those are my expectations in life."

Peter later admitted, "For me, I don’t want this to just feel like it’s all about sex, but this is a big thing. I don’t know how else to do this and I’ll just be honest, but I have been intimate, and I can’t lie to you about that."

Madison walked away from their dinner trying to digest the information and what to do about their relationship. She arrived late to the Rose Ceremony and accepted Peter’s rose, though she did so with hesitation.

Rachel Lindsay made a profound impact on "Women Tell All" when she read profanity-ridden messages some of the women had received this season.

Rachel explained the importance of sharing this information, saying, "We’re going to talk about online harassment, and it’s hate. It’s so unfortunate because people have become so comfortable being mean and meaner than ever on social media. By not talking about it, people feel empowered that they can continue to say certain things to us. If we’re ever going to fix this problem, we have to acknowledge the problem."

Many people, including her husband Bryan Abasolo, applauded Rachel's efforts and the necessity of bringing this subject to the forefront of conversations.

We don’t know who Peter’s mom Barbara is crying about, but this moment has been teased throughout the entire season.
