Back Before We Met

Hermann and Newt are working on a sort of telepathy machine when some miscalculations turn it into a time-machine that takes them back to 2013. Hermann is desperately trying to convince Newt of the urgency for them to return home but Newt is pre-occupied as he ends up bumping into the very girl he's engaged to, a girl he isn't even supposed to meet for another 11 years.
