Jumping from a plane was about the last thing Raph had wanted, but then having to face human judgement and then fighting some alien brain in a big metal suit whilst being thousands of feet high in the sky brought some trauma around to the turtles brain; especially since he had a mild fear of acrophobia.

You visited the lair late at night, hoping for at least one turtle and/or rat to be awake since you yourself couldn't seem to lay your head down and keep your eyes shut. Your hope seemed to work, just not in the correct way as you heard huffs from Raph's room. Panicked or unnerved breaths, as if he was struggling to find oxygen like he was high up, repeating the same thing while he walked back and forth through his room.

"No fear. No regrets. No fear. No regrets."
