[Lancelot actually didn't realize anything was off at first. Most nights are similar to this for him, lying still and awake. Chasing away nightmares before they start; he knows he's not alone at that. The later it gets though... he'll sit up and wonder. Or maybe any impromptu visitors or people passing by in the hallway who also dealing with this little problem may tip him off.
Either way, very confusing.]
Is there something-- going on? [Because he definitely.... had no clue until now.]
