Push her away

Even if you somehow like the thought, that a strong woman like Knight shows affection to you, you need to stay loyal to your girlfriend. So you gently but forcefully push knight away from you, which isn't easy since she is strong like a bull and her armor is heavy.

"Miss, please," you say strict, "nothing against you, but I'm already taken."

"Oh, a loyal boyfriend," Knight says slightly amused, "they are rare these days. Almost extinct."

"Sorry, boy," Vanessa says grinning, "I made a bet with Knight. If you had anything to say we didn't knew already, she would have to kiss you. We have a very stressfull and dangerous job, so I make these little bets to lighten the mood. Despite this, Knights last relationship ended quite ... bad. I thought a good kiss would help her. I didn't expected you to really have something new and important to say. But ... I really hoped for something else you would say us. Something about a very small creature with dragonfly wings on the back? Does this ring a bell?"

"I ..." you stumble, "how do you know?"

“Did you thought you could hide a magic creature from my eyes?” Knight says sharp and crosses her arms, “I just didn't said anything because fairies are quite harmless. Be glad I don't punish you for your lies.”

“That you show mercy is good, but next time hand the fairy over to us!” Vanessa says and smiles a little, “we don't hate them and they are no danger. But you couldn't knew about this. You just helped it because it was small and weak. It could have been dangerous, you know. And don't lie to Knight. When she caught her last ex cheating both him and his affair spend a month in hospital.”

“I know,” you say and look to the ground, “and I'm sorry.”

“You should be,” Vanessa says and takes a step back to show you the door, “but since you gave us some new information, I think we can let this slide and there is no reason to keep you here any longer. Go home and try to get some rest. Our medic team will give you something that allows you to forget what happens tonight. You can take it or not, that's up to you. Some people prefer the illusion of a save and sane world. It makes live more easy. While others risk to face darkness. If you are one of the latter, make sure to not get swallowed by it.”
