Awwww Agape was so much better!

You bring up a good point.
Since we're following what happened after Eros, it would have been interesting to see what happens after Agape's ending. Yeah Rosamund was possessed in that version and captured Ciel, but the take of the new Rapid could have been Ciel managing to briefly come to her senses and trying to fight/save the possessed Rosamund.
But any which away, Mephiste is still hanging around and if stretching to connect him to Ravenwood Manor, it was probably because he was fleeing from Rosamund and either slipped through time to escape her..or somehow Rosamund became immortal and she's been chasing him through out time.
