I don't think she caught it as that when he dono'd it. Plus the other dono that called him out seemed to get sniped almost immediately so she didn't respond to it that either. I assume deleted chats don't show up in vods, but you can see it pop up on her chat feed 3 minutes into the vod with some people replying to it too.
e. If you mean the first Gura sad stream where she announced her graduation then I don't recall. It's way too late for me to go check that vod right now.
