A Special Three-Hour Episode Will Air Monday, Sept. 3

"Episode 505A" - Just when you thought you had seen it all, Bachelor Nation gives you more with a special three-hour episode of "Bachelor in Paradise," airing MONDAY, SEPT. 3 (8:00-11:00 p.m. EDT), on The ABC Television Network, streaming and on demand. After one seemingly solid fellow surprises his longstanding love interest by accepting a date with the new girl, shock waves were sent through Paradise, putting all of the ladies on alert. However, there was nothing that could have prepared one blindsided beauty for what happens next.

An overconfident bachelorette is devastated when her man tells her that he can't give her the future that she deserves. Everyone is shocked when they discover that this couple that seemed so stable has split up and split for the States, separately. Later, things shake up yet again with the arrival of two women at the same time, leading to two more couples threatened when the new ladies take off on a double date with previously spoken-for guys. As the men and their dates enjoy a fun-filled, romantic day on a private island, their ladies back in Paradise fear the worst for their relationships.

Just when all hope seems lost, Chris Harrison shows up with two beloved Bachelor alumni from seasons past who left Paradise twice, firmly hand-NOT-in-hand. Now that they've finally found love with each other, they're ostensibly here to decide who will receive the next date card. Yet everyone is stunned when they walk down to the place where they first met, and the nervous young man asks his girlfriend to marry him. An overjoyed newly engaged couple brings new optimism to the group because if this couple can make things work, anything is possible. Everyone is thrilled for them except for one guy who is forced to watch his ex from "The Bachelor Winter Games" get engaged to another man. Seeing her man slip into a funk is scary for his new Paradise love, who would hate it if this affects their relationship.

With the men handing out the roses, everyone thinks four women will be going home, until Chris Harrison provides another shock to the group with a last-minute arrival from New Zealand. Having just one hour to decide to whom to give his rose, he suddenly becomes the most popular person at the party. After one hopeful woman fails to spark a connection with him, she makes a final attempt to stay in Paradise by trying to steal her good friend's man. Will her scheme be successful, or has her friend, who has been a long-suffering victim of love, finally found the man meant for her?

"Episode 505B" - From babies to bonfires, tonight's new episode airing TUESDAY, SEPT. 4 (8:00-10:00 p.m. EDT), is one that viewers won't be able to take their eyes off of. The fun starts when Chris Harrison shows up with two couples from Paradises past, whom have since wed and had babies, to choose which couple to send on what is promised to be the most spectacular date in "Bachelor in Paradise" history.

The hitch for the lucky couple is that, needing a break, the visiting parents decide to send themselves on the date, leaving their infant daughters with their new, inexperienced babysitters. Will the couple be overwhelmed by the task at hand and run for the hills, or will they enjoy seeing this side of one another and catch a glimpse of their future together?

Meanwhile, the happy families inspire another couple to take their relationship to the next level. When they finally go on a romantic date together, will the man who is lucky in love continue feeling this way when he divulges his true feelings to his lady? Elsewhere, things aren't going as well for another couple and the conflicted fellow finds himself emotionally drained fro m saying farewell to his previous love and unable to be the romantic partner that his new interest deserves. He will have to choose whether to stick it out to see what develops or say goodbye to Paradise.

Later, a confused girl turns down a date with the man who saved her at the last rose ceremony because she can't accept that her first interest in Paradise has chosen to be with somebody else. Then, when the guy she turned down spends the day with another lovely lady and becomes unavailable, he is suddenly a perfect pursuit for this indecisive beauty. Will she be able to cast a spell on the mate who is now no longer interested?

Another woman may be on the verge of changing her mind as well, when a very attractive man, whom she was hoping to meet in Paradise, arrives and asks her out on a date. Although they light a romantic fire that has been missing for the lady, she must decide if it's enough to give up the good thing she already has going with a very successful man waiting for her back on the beach.
