"Sorry I was all hopped up on soda last time, promise it won't happen again"

"Cuz I'm bigger than u haha. I'll have u saying uncle in no time 😁"

U could swap out the "ill have u saying uncle" line for other lines if u want to as well ->
"Pretty sure I could manhandle u quite easily"
"Ima twist u into a pretzel till u give me those candles"

Also should've addressed it when she apologized for falling asleep. Lots of ways u could word it but id prob say ->
"I'll let it slide this one time but only cuz ur cute. Hopefully u didn't dream about me too much"

"Idk u just look like u rob banks for fun 😄"

Or maybe like
"Idk u just look like u would be a good partner in crime 😊"

"How is our romance going to blossom if ur never here?!"

"Too late I've already planned out our entire night 😅 hopefully u like drinks and witty banter with handsome bearded men"

Just use what little time u have between when she gets there and when class starts. U could even tease her for it - u could be like "wow someone's cutting it close, u must like living on the edge".

Why can't u talk to her after ur done working in ur project groups??

Or give em a taste of their own medicine - "is that ur pickup line?? 😁"

"Is that seriously all u have to say?!"

"Lol are u gonna make me pee in a cup too?!"

"I know how to treat a lady 😁"
