>>255 - >>258 He seems particularly thin at the moment (I'm trying to relocate some of the "candid" standing shots of him in knit top and jeans from the LA press junket - his waist looks tiny in those). Could be for Gucci, though since his suits from them are custom-made, they should be able to adjust for any slight variations in his weight. I'm guessing it's more from lots and lots of running (which I think is his stress relief), plus not currently working on a role for which he needs to bulk up.
The pressing question - is he currently at his Loki weight (for the rumored IW filming soon)?
