Regarding the Tardis locking Clara out:
At first I just thought it was doing it so she would help Merry face her fears in order to save the 7 worlds instead of running away.
But after reading speculation and conclusions here:
Perhaps Clara is Jack's daughter or niece or sister? She looks a lot like John Barrowman. Or maybe she could be his alter ego like Rose Selavy and Marcel Duchamp, except they would be actual, different people.
the dad even specifically brought attention to -if that particular leaf at that particular moment hadn't etc.
Yeah, I thought for sure that uniquely red leaf was an evil leaf, but it turned out to be a more of a magical, special leaf.
That's my question, too. Eleven said to "take" his memories, so would they be gone? Didn't seem that way.
And so did he lose some of his memories? Did the alien eat them? Will this be a plot point later?
In an episode where a sun implodes and nothing much happens, I guess the memories plot will not carry over to future episodes (or even the end of this one) either.
Matt did give off some evil creepy vibes a couple of times. I felt like he was auditioning for a serial killer show.
