I watched to pp1 demo. To me it didn't have anything that suspicious.
The one i found bad, [didn't mark a time] They are all sitting near bd ent lining mid, then shockwave turns and sprays gap right when Jusu comes up gap. But that could also be from common sense of everyone is lining mid so watch there. I found it sketchy. But i don't think he was walling. But that's just my opinion.
