Raph’s always been a bit paranoid, when it came to safety - it was a given by now. He was constantly worrying about his brothers, and… you, just as much as them. You’ve been his best friend for ages, after all. And, as of late, that paranoia hasn’t exactly decreased. If anything, it’s gotten worse. That was to be expected, when the foot clan was a lot more active.
…And so, here you were, in the lair, waiting for the turtles to get back. You scroll mindlessly through your phone, feeling rather bored. That is, until the nearest manhole opens up, and the turtles climb down. You put up your phone.
Almost immediately, Raph is coddling you, making sure nothing happened while he and his brothers were gone…
…And then he sees the cuts on your palms. How many times now had he told you to be more careful while messing around in the training area? Too many to count.
