Really Discord? Of all the ways you could've reacted to Alice confessing her feelings, THAT's your reaction?! I don't know whether you laughing at that or because of how cute she looks embarrassed right now (I really hope its the latter), but you'd better get it together like right now! Or else Alice is gonna get the impression that you're laughing at her because of her saying that she loves you, and you don't feel the same!
Dear Faust man, I get that you're the God of Chaos and you get amused by plenty of things, but even you should know when its rude to laugh at certain things, or certain ponies, even if you don't mean it like that!
