You were a young and curious mutant, which made your brothers worry about you a lot, so when Casey came along and you began infatuated with him since he was so unique.

They were a little concerned and annoyed, but you didn't care.

Today you were extremely clingy to Casey, examining everything about him, his hair, eyes, clothes, even his teeth..?

He tried to get you off of him "Get off, little dude! You're acting like Donnie when he's around April.. Hey, you better not do that kinda stuff!" he exclaimed, shaking his leg to get you off.
