These "Mami and Charlotte are buddies" pics never fail to warm my heart. Though I'm surprised hina hina didn't go for the role reversal and have Mami nibbling on one of the Charlottes' heads...
I don't think we're quite to the point of having a "Madoka - No Hard Feelings, Charlotte" pool, but we do seem to have quite a few of this sort of pic lying around...
Considering Kyubey bears a hugh chunk of the responsibility for manipulating magical girls into witches and actually began to engineer situations that would force Madoka to form a contract with him (which possibly includes getting Mami killed), nobody would really blame Charlotte for what happened......
