You and your sibling are collecting souls contracts for him in order to keep yours. You didn't know this, but he watches you and your sibling fought bosses 20 times your size. He chuckled as you and your sibling hide from one of the bosses, panicking. You look out for the hiding spot to make sure the coast is clear. He took a sip of wine from the glass beside him on a little side table. Ignoring the women almost begging for his attention, he's too busy, watching you and your sibling fight. It's entertaining.

To him at least it is.
