Part of Marco really wants to keep needling Rachel; there was definitely something not lining up right between them, and instead of opening up to her and filling her in right away, it makes him want to just keep pushing until she gives up the information he wants.

But who is he trying to kid? This is Rachel here, even if she was from a bizarro world where Letterman and Leno's boardcast slots were flipped or something stupid.

"Okay, let me take a complete stab in the dark here. One moment, you were minding your own business, running from crazy brain-stealing aliens shooting at you with ray guns, and the next moment, you're crammed in a little spaceship with a bunch of strangers who dumped you out here and told you to get a job?"

And with that, he'll try to swing his free hand over her shoulder in a rather friendly manner. "Come on, Rachel. Chill pill. Dr. Marco prescribes two with every meal."
