“I’ve been icing it and doing all the exercises, I don’t know why it got worse,” Dick insists as you examine his shoulder.
A little white lie. His fight with Bane last week had... well, unintended consequences for him, especially his already-injured shoulder. Being repeatedly slammed into a concrete wall and then being thrown off of a roof definitely went against his physical therapist's advice.
But he had been listening and doing everything you said–except for not straining his shoulder. It isn't like crime takes two weeks off so he can heal.
You don't know he's Nightwing–how could he possibly offer a valid excuse for this?
It’s then when he realizes just how close you are, and he offers you a sheepish grin. He's practically begging for you to believe him. Especially since you're really cute, and he can't look like an idiot in front of you.
