is it me or are they most likely dead
It could go either way. I'm assuming they died in my play through because I sent them and Clem back to the train and Clem still ended up alone in final scene. Not to say I wouldn't love it if they'd lived; Omid was my favorite group member (outside Lee and Clem).
if i had to guess on them being alive i'd wager they missed each other at the train. i dont want them to be dead but clem being on her own doesn't seem like good news for them but they did survive the whole time on there own before meeting lee, plus i told them and clem to stay out of cities
It's just you, they should be alive. Shes pregnant and Telltale can make many stories with that alone.
