[her eyes widen at that, both because it jogs her memory about where she heard Sam mentioned before and because she never expected to hear that name spoken aloud] Yeah, now you mention it, it was. But I didn't think he ever gave out that name.

[from her confused tone, it's both clear that she knew him as Gabriel and that she didn't expect anyone else to. after all, it's a name she never told anyone; it wasn't a risk she was willing to take after the mental torture he inflicted on her just for learning he was an angel. she was afraid anyone she told might suffer similarly. and even now, when he's been gone for so long, it's still something she's never brought up. if she's honest, talking about him at all is strange]

Ahh, you're one of those. [she nods, understanding now why he's looking for changes on the Plane] I tried to find you once. 'ad a merger with--Gabriel. [she can't help but hesitate before she says the name; it's odd to actually use it] Ended up with some, ah, vengeful spirits where I'm from. He said you were a...hunter. And might be able to do something about that. But I never ran into you, and...well, they disappeared after Gabriel did.

[there might be a very slight hint of regret in her tone when she says that. she still doesn't understand why she would possibly miss Gabriel, but it doesn't make it any less true that she does. they had that merger for a reason, after all]
