This is a reference to their interaction in the League Club Room.

Jacq: Thank you for always patching me up when I take a tumble, Nurse Miriam...
Miriam: Oh, it’s no big deal!
Miriam: I mean, it’s not like I’m just gonna stand there when you take a fall like that right in front of me.
Jacq: Haha... I guess not.
Miriam: But honestly...you really oughta be more careful, Mr. Jacq!
Miriam: I think the only person who gets more scraped up than you is Dendra...
Jacq: Oooh! You mean when it comes to injuries, I’m in second place?!
Jacq: I guess I’ll need to work hard to reach the top! Right, Nurse Miriam?
Miriam: If you’re gonna crack jokes about it, you can get scuffed up for all I care! Be serious!
Jacq: Yes, ma’am...
