Tom was hitting booze hard during the first reunion, because he felt awkward as shit. (I love Reading 2010 tho, especially Not Now - fight me)
He clearly isn't doing that here. Throughout Lolla he was rinsing his throat spray. Dates have just caught up with him. Anyone that has ever drunk an iota can probably see it isn't that. Not that that's something to be proud of, just realistic.
I've had two halves at a brewery whilst doing work....whoops
Sober by 29...maybe
