Kind of fun, but similar gotchas to last week's IMO. They set stupid rules, gotta stick with them.
All rooms reset - entirely pointless rule, and doesn't actually affect the teleporter (you could have juggled with the buffer or something). But that's what they said. Except diamond room apparantly doesn't reset.
Also, if it were diamond, I don't care how hard you punch, nothing is going to happen, why not just make it Quartz or rock or something that would still take millions of years to punch through? And use the heel of your fucking shoe you muppet.
Lastly - if it took him 2 billion years to get through, then he'd be diving out of the window onto a very high pile of his skulls. They'd have long since risen out of the water.
Still, we get it, he is really determined (even though as he doesn't seem to remember each hardly purgatory. Rory still owns the 'doing something for a long time' record in my book)
