Just imagine Varians reaction when he finds out about Anduin and Wrathion 

“Hey Dad, I know that you were like, split in half by a black dragon and stuff – well, I have been too, hurr hurr hurr. But no really.”

I am pretty sure if anyone is going to be doing any splitting it’s Anduin:
Anduin Wrynn says: Who do you think – wait – <name>, look out behind you!
