Isabelle is about to move on, but the name catches at something in her brain and she pauses. She doesn't know Tim very well at all but she knows the name Steph well enough. She remembers the way Billy had been when she left, so utterly distraught to the point where he wanted to fight her.

She knows that Billy and Tim are friends, obviously, but she never knew they were that close.

"Not Steph as in Billy's Steph?" she asks, just to make sure. She could be totally off base, but somehow, she doesn't think she is.
