An 'EXO 90:2014' rep quickly responded to Ten Asia on the 10th, "Since Luhan is the lead star for the upcoming broadcast, inquiries are coming in concerning it... However, because it has already been filmed, it will air as scheduled. We have not discussed anything concerning the following episodes."
Also, in the midst of all this fellow EXO-M member Lay just updated his Weibo with a message that fans speculate is directed towards Luhan.
"Brother goodbye! If we have the chance let's stand on stage together again. As brothers, I support your every decision. Good luck".
Lay was also asked in a fan chat session the other day about Luhan's status, and he had said that Luhan was doing well and resting. So now judging by this update, it seems the members may have been well aware of what was going to happen today.
