The Doctor was sure he had heard something outside. He stood with his ear pressed to the door and listened and when someone tried the door, he jumped a little. Pressing his ear to the door again, he calmed and waited. The door shoogled again, this time someone was trying the lock.
He stepped back and unlocked the TARDIS, opening the door to look out."Heee.... llo..." he said, looking at the two. One he saw on the comm, but the other? No, this was just getting silly. His previous self was here already and now an even younger one?!
"This is awkward..." he said running a hand up and down the lapel of his jacket nervously.
