At this stage, I'd take either Adam or Jake - in that order. Closure comes in fanfic, but we can always give the writers the benefit of the doubt they have a surprise up their sleeve!

I can understand people's hesitation to write Adam. For his three appearances, we've only met him once; but sometimes that's all we need to draw our own conclusions. ;) Especially when canon refuses to clear the air. But yay, I'll have another look at the meme for other things I can fill!
