↓ Transcript
[Damian's face goes from in thought to a cheesy yet ashamed grin]
Damian: Or maybe... she hates me... cause I am Young?

[Ash puts his hand to his chin and thinks about this, though Damian hovers nearby with finger guns and cheeky grin at the ready]

Ash: Yeah, that makes sense... she doesn't seem to treat us younger staff very well-
Damian: My surname is Young.

[Ash flips to absolutely disgusted anger and Damian weakly backs off]
Ash: DID YOU JUST DAD JOKE ME WITH YOUR SURNAME?

[Damian turns around and briskly strides away from the small ball of rage behind the counter.]

Damian: uuuuh yeah well you've been great at closing down and all that so - uh- you'll be fine! You don't need me here so I'll be off!
Ash: COME BACK HERE AND FACE YOUR PUN CRIMES!
