I actually have a lot of episodes to blog about. So this is the one where the weird thing who zips herself out of the human body and farts a lot comes back. Long story short (w/spoilers!), she gets captured, tries to get the Doctor to let her go, opens a rift, which is going to tear the world apart, but then the Doctor does something cool, and it closes, and the weird (and insanely annoying lady) gets turned back into an egg, for them to return her to her planet to be "reborn" and have a new, hopefully better life. The end.
P.S. I didn't love this episode, especially cuz Mickey is starting to get on my nerves.
