((MAJOR SPOILERS))
Jenna's good ending was amazing, I love how everyone got along near the end, and how Micha unexpectedly fit in kind of! poor Flynn, I can guess what he was going to hear when he left, but that diner and the group's atmosphere was so blessed, the group was together without much quarrel for once! and Leo's little smile near the end was a perfect touch
Jenna's bad ending felt weird and short at some points , if chase said he was bi, I expected that he might at least be allowed to be there with her when she tampered with the dam, nevertheless, what the entity said by the end was satisfying "i suppose you won't be coming back", Jenna actually buried the unsolvable puzzle, she actually defeated echo in some manner! but by giving it too many sacrifices while doing so, and most likely her future as well, if she survived or found a way around the flood to manage and leave , she would most likely be arrested for life.
Evil Jenna was an unexpected, pleasant surprise nevertheless, seeing someone so collected, cool-headed and the most rational person in the group going chaotic like that, I dunno, I enjoyed that concept for some reason, not to mention how Flynn's shakey behavior after what he did proved parts of his personality so well, he has become even more of a favorite in my book.
