Slayer was.... content with his life. I mean, who wouldn't be in his position? But he was... bored... lonely. He wanted, no, needed a companion or sorts. Sure, humans were fun to tryst with. But they died far too quickly for his liking. 80 years was a flash in the pan for him, but for a human it was their whole life. He'd began to lose hope, thinking he'd be resigned to a life of short lived romps and watching those he'd grown fond of die... not to mention who whole blood thing... that was until he'd heard word of someone immortal. Not a gimmick that allowed one to live as long as they weren't killed, not a faux costly immortality like he'd so often see... truly and permanently immortal, similarly to himself... he knew he needed to find them right away, it was almost as if fate itself was calling him to them.
