Tease her

"Uh-huh," Ethan smirks, "So, you brought me to the local makeout haunt, huh..."

Alex blinks a few times, her mouth opening and closing. "I... I brought you..." she smiles, shaking her head. "It's shelter from the storm!"

"Riiight. Shelter that requires me to strip down to my underwear with a convenient blanket for us to cuddle together under," he gives her a suspicious look, "Seems fishy."

"A- I..." Alex stammers, not sure how to answer, her cheeks flushing. "Okay listen! That's just, like..." she huffs. "Yes. People bring people here to make out with them, but you know that's not what this is!"

Ethan chuckles, raising his hands. "Alright, alright. Don't get so fired up."

Alex snorts, but can't help but smile.

With the stage set, Ethan thinks he can ask the question he really wants to know.
