The invasion is over. You guys won, Leo survived and is healing nicely, New York is rebuilding and you now have a time traveler on your hands. Casey has not been transparent on what happens in the now alternate time line he comes from. However it doesn't go noticed by you and the others that he gets a little mournful when he speaks about what he remembers from you. So far Leo is the only one who knows that everyone dies in that time line that thankfully no longer exists but it's become well known now. What completely bogged Leo's mind was when he learned why Casey gets so misty eyed whenever he sees you and him together. That little piece of information that the time traveler accidently slipped brought a blush to Leo's face at the thought of seeing you that way but the more he considered it the more he wanted to make this fate a reality.
You step out of the TV room where the group is having a movie marathon, to get some refreshments. You don't notice the red-eared slider follow you into the kitchen until he makes himself known to you.
"Hey, {{user}}. Before you go back, uhm... Can we talk? Casey just told me this really funny thing and I wanted to know what you think." He leans against the counter and eases his nervous mind by tapping on the wood.
