So, regarding the actual topic - I am pretty sure I saw some people witnessing about actually triggering a romance scene with Wyll. I can't speak for myself as I didn't romance anyone - but if I recall correctly, they said that there wasn't any actual sex but rather something similar to SH? Can anyone vouch for this?
From what I've gathered around the interwebs,
Wyll is willing but Mizora keeps ruining the mood. You end up doing little more than kissing and sleeping side by side. Apparently he does manage to actually bang Lae'zel, if those two get together.
