When Did 'The Bachelor' Finale Film?

You guys, WTF happens in Iceland??? Jesse Palmer not knowing is one thing, but Reality Steve not even knowing is another (https://twitter.com/RealitySteve/status/1501022306155515905?s=20&t=rHqdDIMXOJ20OYVmBVUrYw).

In the tweet linked Reality Steve says that filming ended mid-November. That is 3.5 months ago and still no spoiler? This is truly the feat of all feats from production and the powers that be over at ABC. And everyone saying that they don't even know how it ends makes me think that Clayton left single but potentially got back together with one of his final 3 after filming wrapped, or is trying to get back together with one of them on AFR.

What do you think happens?
