He'll definitely not be on BIP, as it's filming right now and he's most definitely not in Mexico. Also even if he didn't win, he's likely Final 2 and the Final 2 never goes to BIP because it will obviously spoil that they didn't win.
I've seen this comment on other boards and I don't really understand it. Tyler didn't get much airtime to this point because there wasn't much to show. Hannah has admitted in one of her media interviews that Tyler was one of the guys she never got a chance to talk to on Night 1.
So other than his coming out of the limo and meeting Hannah there really wasn't much to show of him in the first episode. I'm pretty sure he wasn't involved in any drama and so since he and Hannah didn't even really talk that night, makes sense he wasn't shown.
The second episode, again he didn't get alone time with her after the whole Cam thing. But he was visible throughout the date, giving ITM's and of course the hilarious walking up to Cam. And while he and Hannah didn't have a moment during the group date, they talked during the cocktail party, when Hannah talked about liking how he looked at her. Hell Episode 2 is when Tyler first made an impression on me.
Third episode, again they showed some of their alone time during the group date and of course this past week he had his 1 on 1. The fact is Tyler is not involved in any drama a la Luke P. so we won't get airtime from him on that angle. Hell I don't think he's even been on a group date that Luke P. has also been on.
Jed spoke and sang to Hannah on Night 1, he was the one who had the awkward moment of walking in on Hannah taking off Luke P.'s shirt and his being so sweet and understanding about it. So of course we've gotten to see him a bit more.
And with Peter, I don't think he's been shown so much more than Tyler but Peter had that weird drama with crazy Luke P, he was one of Hannah's standout conversations on Night 1, he does cheesy, "good television moments" like asking her to be his girlfriend and so of course he's shown more.
All that said, I don't think Hannah's attending CMT Fest and being in Nashville, where Jed basically lives, is proof they'll be together and she picked him.
They always push the leads, especially the Bachelorettes to make these types of appearances and Hannah's a Southern girl through and through, so you know she probably loves country music and CMT Fest is a good fit for her. She'll likely only be there for a day and a half.
What is suspicious about the spoiler is that it continues to look like she and Tyler have had no physical contact since filming ended almost a month ago. And that's long for a lead and their F1 to not have a safehouse visit.
The July 4th weekend will be the key I think. That is almost always without fail a safehouse weekend. If Tyler is fully accounted for and for a guy who clearly loves boating with his friends, you know he'd be out there grilling and stuff during Independence weekend, then I'd say there's no way the spoiler is right. And if all parties are accounted for, I'd say like some suspected, she didn't pick anyone.
