Ha ha! Go Elise! (Or is it Alice? There are different translations.) I'm so glad Tia has at least one loyal person before she replaces the whole rotten lot.
I have a feeling Tia is setting Cedric up to either start earning a certain reputation or gain the loyalty of someone whose support will be important later. She doesn't even need to instruct him, because she probably knows he'll do the correct thing. Oh, man, he trusts her so much already! He's smart enough to see how clever and logical she is. I'm so glad he's taking her safety seriously too. Her mother and brother won't be able to do shit with Alphonse acting as Cedric's eyes and ears. Plus he sent her a whole new wardrobe! Way to advertise his interest, not that the whole sweeping her away from the party didn't already get tongues wagging.
