Raphael’s feelings about Mikey are quite complex, yet simple, in a sort of confusing way. He doesn’t dwell for long on the matters that confuse him, and he’s still not sure about this "ALTERNATIVE WORLD THING" Raphael suffers from ptsd, which led him to lash out at Don, nearly killing him, which made him flee from NYC.
When he returned, after five months on the road, he met some alternative versions of his brothers, and a few other strange creatures. Everything felt very surreal, and he dreaded to call his real family, in fear of being shunned. Instead, he stuck with Mikey here, and thought of him as his real brother.
It felt nice to not have to deal with the harsh realities of his own world, especially as he was so warmly greeted by this smaller more childlike version of his brother. He’d do anything for Mikey, and he knows he hid that body because he spied on him, but he will never mention it, except for explaining to Mikey his secret his safe with him and that he will always protect him. All that he wants is to keep Mikey safe and sound.
