Going to have to agree with Shinta. Fantastic episode.

Rem is the best.

I can understand the anger at him rejecting Rem, but it wouldn't make sense for him to just drop all of his feelings for Emilia.
Hopefully after this, he'll either:
A) Realize that Rem is the best and get over Emilia
B) Get both. At this point, Rem is in the bag. Might as well grab Emilia too.
