lulz, I don't understand why and how Jack of all people has it? My mom was in the room when I saw that and I was like, "DID HE JUST RUN FOR THE TARDIS LIKE, 'DOCTAHHHH WAIT, I HAVE SOMETHING OF YOURSSSS'"

I also don't understand why he was so DISTRAUGHT when the jar broke in TW. Jack, wtf is your problem. You... are scaring me with this Doctor bullshit. Like, seriously, I think every companion probably has Stockholm Syndrome.
