Valerio's Links
Before meeting: Completely unaware of Samael's existence.
First real meeting: He thinks Samael is really offputting, but still tries to be nice to him upon learning they're technically related. Once Samael's behaviour towards him changes though, he starts to try and avoid/ignore him.
After getting used to eachother: They get along better, but that awkwardness between them is ever-present and Samael doesn't seem to want to let go of his stupid grudge any time soon, so Val still just tries to mind his own business and avoid interacting with Samael too much.
Before being expelled: Completely unaware of Val's existence.
First real meeting: Upon learning he has an extra brother, he latches onto him fairly quickly. Once he realizes Valerio has been around Asmodeus more than any of the brothers, he forms a stupid grudge against him.
After getting used to eachother: He's fine with being around him more, but he still gets pissy thinking about how their dad must value Valerio over him. He wants to be more important to Asmodeus than some random non-blood-related human is. He thinks he deserves the attention far more -- He doesn't realize Val and Asmo's relationship isn't the greatest.
