"Bachelor in Paradise" Season 4 had a condensed shooting schedule, with each episode s-t-r-e-t-c-h-i-n-g out the drama to ridiculous lengths, so it wasn't a shock to hear that it wouldn't end with an engagement. But! There will be a reunion show -- taped last night -- and one couple got engaged.

You can guess which one, right? Let's just say it's not Dean Unglert and Kristina or DLo.

It's Derek and Taylor.

Yep, according to Reality Steve, Derek Peth of "The Bachelorette" Season 12 and Taylor Nolan of "The Bachelor" Season 21 are now engaged.

Steve had said the finale reunion taping would be Wednesday, and he updated on Thursday with the big result:

Us Weekly also confirmed, with a source telling them "Derek and Taylor got engaged last night. No one knew Derek was going to propose. He gave her a Neil Lane ring."

If "No one" is the new "everyone," then yes.

That reunion special should also let fans know how the Dean love triangle is going -- last we heard he was still sort of dating both, spending a lot of time with DLo in Los Angeles, despite telling DLo that he loved Kristina.

Chris Harrison had previously explained to Entertainment Weekly that "The live [finale] at the end will be more like After the Final Rose where we're live, the show is wrapping up, and there will be people involved that were on the show because we have to find out where everybody is. [...] It's going to be a lot of finding out what's been happening because things have been continuing back in the real world since the show wrapped up in Mexico. It's going to be interesting and I think a lot more fun for all of us. It's going to have a live studio audience."

But it obviously won't be completely live if part was already taped last night. Also, this might be related to Mike Fleiss tweeting about "shocking news" regarding "The Bachelor." Should we expect that big announcement during the live show?

"Bachelor in Paradise" continues Monday at 8 p.m. on ABC.
