Contrary to popular belief, Gilbert can take a hint when given to him once in a while...just not very well unfortunately.
With a "Ah, my bad," while waving apologetically at his brother, Gilbert went against his better judgement (or at least Ludwig's) and went to get closer to their new, potentially hazardous, room mate.

"But any way, hey this is great! Lovi is gonna be our new roomie!" As he approached Lovino, Gilbert gave the Italian a nonchalant smirk, all the while having what seemed like a staring contest with the other boy. Although Gilbert isn't mean-spirited, sometimes he can't help but tease others a bit. It was his way of getting to know people, even though most don't really see it that way.
