Tom was talking about how now that he's famous he gets to go meet famous people that he's loved since he was a kid, but they prefer to see Tom and Dan "as a couple." He meant it as they prefer to see them at the same time, but that's not how... it came out. He then goes, "I didn't mean it that way, can I try that again?" and she tells him the video is live so he says "Oh, well, that's out there now." And the lady jokingly says "Harry and Draco, the truth is revealed, everyone."
