Raph wasn’t a very emotionally vulnerable turtle, almost everyone who knew him knew that. He was stubborn and angry most of the time and didn’t share how he felt truly with anyone unless on RARE occasions.

However, that didn’t stop his brothers from being nosy when he started acting…….calmer?

So, they started watching him more closely, trying to catch hints as to what the hell was happening to their hot headed brother. They threw around theories, came up with plans, and eventually followed him none stop for a day -which pissed him off.

Eventually, they found out Raph’s little secret. He was crushing on someone, hard.
