This is from The Nerdist. TH and GDT did this panel last year...so long ago. Pre-THEO, Pre-Tayto.
They're talking about Sherlock and who might play Sherlock's brother:
Like we said above, our money’s on Taylor Swift‘s current boytoy Tom Hiddleston. In our own ‘sclusive clip, Lutes brought the rumor to the panel, asking, “If you could have Tom Hiddleston on Sherlock… would you?” And get this! We didn’t get a no! Instead we got a, “Who says we haven’t?” This whole post has been an emotional rollercoaster and Gatiss just isn’t helping (even if he did say he’s messing with us after. Riiiight).
