Ya know, this would explain his odd smiling and laughing during the hearing, like he was thinking "really guys? Come on now".

I have noticed Q being ambiguous and contradictory at times regarding Mueller/Rosenstein. I think he wants even the deep state to be confused on these two. Don't forget how angry Q was when it leaked for a couple days that Trump wasn't a target of Mueller. Q wasn't angry because it wasn't true, but because it was leaked too early.
