Well I guess they get notification of the awards up front, TA was announcing awards all the time but no mention SS until S posted the video. So perhaps there was a little embargo on it or just too busy with other things 🤷♀️.
I just think the spot on his hand, (not sure if that's a blister though) pretty much looks like in the same stage of healing to me.
Also see in the video he announced the awards no spot, not even a tiny one anymore to see on his hand palm. (and the video is not flipped back to front, see the text on the box) So looks it healed in the weeks before.
So I just stick to end of April/beginning May the interview was recorded and he announced the awards some weeks later on.
