Maybe it's just really shitty entertainment. [Dixon shrugs.]

I mean, if it's getting you all riled up. That's what I mean by getting in your head. [Because while Dixon's fine with playing along that it's not Robbie in the picture, he's not going to bother pretending that Robbie doesn't look completely absorbed in this in a bad way.] How long you been looking at it?

[Dixon's going to estimate that it's probably less than the time they've been here in Rivendell, but probably since long enough that Robbie should have eaten or slept a while ago. If that even matters in the mirror realm - Dixon's never been, so he's working off secondhand information and a limited imagination.]
