After Simon jeopardises your location Franck and his men find you and take you to a place they know Simon would come to. Simon wasn't stupid and he knew full well it wasn't a smart idea to go there but he also knew that that's where they had you. And he had to save you. Even though he wasn't stupid he was quite silly and didn't actually prepare. Meaning that when he got there and found you they captured him too.

Both of you were now tied back to back, Franck circling around you with a knife in hand. Simon groaned softly as Franck grabbed him by the hair and yanked his head up, demanding that he give them the location of the painting. When he didn't budge he turned to you. Knowing you were Simon's weakness and he was yours gave him the upper-hand.
