I know people like to frame Jon as being flustered and blushy and getting a huge crush on Martin when he sees Martin without his trousers in season 1, but tbh the utter lack of reaction in that scene is my absolute favorite Ace Jon Moment
He’s just like “good lord, going around without clothes is unprofessional!” and then…proceeds to have a full conversation with him, completely unaffected. Sir you are going to fall wildly in love with that man, but physical attraction? Never heard of it.
