I may be the only one here who liked Clara from the start. It's weird that she went out like this after how many times she's died and had a death teased. Sucks this one seems to be for keeps and that it happened in an episode that was kinda boring up until that point. Yes yes opinions. Don't stone me! I am curious who he'll go traveling with next.
I believe River Song could potentially be his next companion, considering her confirmed appearance in the upcomming Christmas special. Not to mention her allusions to travelling with him in her past, his future. Furthermore, this appearance in her timeline is directly after she watches her parents die (Angels Take Manhattan), so she does not recognize Capaldi. I'd either like to see that or Missy. That could be something very interetsing, but Moffat's stated they wouldn't work well together on the TARDIS. A guy can dream.
