Derek blinks a little, surprised slightly when she says that she's never the term Alpha before. She's comfortable with wolves but doesn't understand the pack dynamic, which takes him off guard a little.

"Oh, uh, it's the leader of the pack. The Alpha is the one in charge. The one that should be protected at all costs. They're the dominant one in the pack. For werewolves, the Alpha is the one who can create new werewolves, has the most physical strength, and leads the group," he explains, wetting his lips. He's wondering how much of this he should really divulge, because some of it isn't wolf specific so much as werewolf specific.

Clearing his throat, he decides to wait to see how she reacts to that bit and whether she appears to be more interested in the additional information he could add.
