Theseus threw Ariadne a wink, still showing after all this years he could have a thing for her if the door were wide open. He was being drugged that was for sure, he literally slid down off the bar to find a couch or something, but there was a moment the lights hit his eyes and he thought he could see Dionysus from a distance. That he hoped was a hallucination.
He stumbled his way through a few customers landing on the couch. It felt like he was out for five minutes, but it was more like half an hour. Dionysus did come in, greeting his wife with a kiss. As soon as he noticed the brute in his personal space he got defensive.
