Hearing Zee yell he thinks to himself "stop yelling stupid stuff and help fighting"
However his voice sounds different then usuall, and he see's Gilchan walking towards the door and having the intention to open it.
Ranor will hold action until Gilchan opens the doorusing the shove from Rybian to go through and hitting him on the back of the head with the quarterstaff, making sure he is standing in the opening of the door blocking Gilchan from closing it again.
