Moebius is a horrid, HORRID episode!
In the episode 1969 Sam didn't want anyone doing anything that would wreck the timeline and all this shit.
Yet here comes Moebius and Sam is like "Hell yeah! Let's go back in time! Who the fuck cares?! No one will notice little old us! Fuck the timeline!"
It's just a lame story setup so we can get a bunch of one off jokes. At least part two has an awesome ending.
