Gibbs- He'd stand in the doorway and stare a little bit
"Sorry (Y/N), should've knocked"
But when you turn around he'd smirk to himself and close the door
Tony- Being the 'charming' man he is, he'd grin and apologize
"I'm sorry for barging in (Y/N)... but you don't have to hide anything from me"
I'll leave you to what happens next ;)
McGee- You were spending the night at his house and you were changing. He got really embarrassed about it
"Oh my God, I am so sorry (Y/N)... I didn't mean to look. Well I mean I don't mind looking at you... You know what I mean"
You smiled and shook your head while he closed the door
Palmer- His eyes would go wide and he would get nervous
"Oh jeez, sorry (Y/N)! I only saw your legs! Honest! Next time I'll knock"
Ziva- She'd try to pull herself together and play it cool
"Oh... I'm sorry... how impolite of me (Y/N... I'll wait outside"
Abby- As she'd walk in, she'd be mesmerized at your beauty
"Oh! Sorry (Y/N)... I didn't know you were in here.."
As you turn away, she'd smile to herself
