Wow. That's really awesome that Lucy got a TARDIS key from the Doctor. That means she's definitely a close companion now. I think Lucy really needed that hug from him. I like how he and the Master are complete opposites in personality.
Author's Response: Yes, that's why it's fun to write more of the Doctor once in a while. He can be a right prick, too, but he's still a lot kinder and softer than the Master. And especially ten is very hug-able, lol
