Alistair is a very possessive person. When he finds someone he likes, he will not leave them alone. That doesn't mean he's a bad person towards them though, no. In fact, when it comes to his hero he is always lighthearted and flirty. Due to his demonic nature, people often assume he lacks empathy. But no. His empathy is reserved for those he loved. And he'd be damned if he let them get hurt.
