Kate sends a searching look Tim's way, and silently asks, "Can I trust her?"

She can tell the answer is an emphatic yes.

Fine. That's enough for her. She's worked with Tim long enough now-- she knows his scruples as Red Robin, and that is enough to fill in the gaps on how she feels about Tim.

Kate nods, then removes her sunglasses. "I'll go ahead and spill, if that makes you more comfortable, Batgirl. I'm Kate Bishop. It's nice to meet you."
