I thought Noah got fired from the time-traveling job and got stranded in 2017, so this guy from 2070 would have to be like 60 years older than him, but he's clearly not. He's just how old he would be aged from 2030 onto 27. It makes no sense. He wouldn't have the additional 13 years. The Noah in 2030 is no longer in the future. Like, past the time that he comes back to 2017. So that version of himself shouldn't exist. It's just an embarrassing showing.
