A returning bachelor is rumored to be the recipient of the final rose in this year's "The Bachelorette." 

Recent spoilers for "The Bachelorette 2015" episode 4 claimed that Nick Viall, a contestant who failed to get Andi Dorfman's final rose during last year's rose ceremony finale, will try his luck this year to capture Kaitlyn Bristowe's heart. 

In the sneak peek for Week 4 shown on Yahoo! TV, Kaitlyn talks to Nick while she and the other bachelors are in New York. Then she tells the guys about Nick's return to the show, saying that she met with someone she "had talked to before I came on the show." 

She also admitted that she and Nick exchanged words on several occasions, and that she would want to give him a chance if ever he decided to return and join "The Bachelorette" this season. 

There are also rumors claiming that while Kaitlyn and Nick never had a chance to meet each other personally, the two were very flirty with each other and made quite a connection. In addition, there are several reports claiming that Kaitlyn met with Nick after she informed the current set of contestants about him, and the cameras trailed behind. The two were seen sharing a passionate kiss after that. 

A source recently told E! News that the two were really friends even before Kaitlyn agreed to do "The Bachelorette" this season, and they were slowly developing feelings for each other. When Kaitlyn decided to do the show, Nick also expressed his intention to come back to try to win her heart. 

"He decided he wanted to do the show and pursue her. His attitude was, you only have one life. But he weighed the decision seriously," the source told E! "There was a lot of deliberating. If she had started to develop feelings for someone else, he didn't want to ruin it for her. He genuinely cares for her and wants her to be happy." 

Could this mean that Nick will be the runaway winner in "The Bachelorette" this season?

"The Bachelorette 2015" episode 4 will air on Monday, June 8, on ABC.
