I wonder what "it" is...
Also, it's weird that Jemma didn't tell them about astronaut dude right away? Why wait?
It's also funny how he doesn't have freakishly long hair and a massive beard. If you spend fourteen years on a lonely planet surely you'll stop giving a damn about shaving
I guess they had to keep him reasonably attractive instead of a caveman for Jemma to want to dance the mattress mambo with him.
Also, monolith. 2001. Reference not lost on me. ;P
