Obscurus Lupa saying that you may remember John Barrowman from Doctor Who, but you "probably don't" remember him from Torchwood bugs me. I know it didn't get a serious audience (at least in the UK) until its third series, but... I dunno, there's something...off.
That's why she said "probably" and also why it was a joke.
Yeah, but the joke still bugs me. And it bugs me why I can't pin down what bugs me about it.
I took as a bit of sarcasm, because everyone knows John Barrowman was in Torchwood. Seriously, I've never seen the show, and I knew that because of fandom.
