Marco asks if he can help Zoro. Zoro needs to get to the roof. Marco can fly. It's obvious
My boy is back yep!!
There are 3 scenarios:
1)first Marco ll help zoro getting to the top
2) King ll intercept marco and Zoro and Zoro ll fight king or marco ll fight king
3) Marco ll help choper and fighing queen, Zoro ll move with drake.
Nothing else make sense atm
by the way, my boy one shotted a guy that is stalling hybrid drake form. Zoro one shottted this supernova which is insane not even kid was able to do that not kid (the so call rival of luffy). Zoro is almost = to luffy no doubt
