When Dr. Orton smiles, the corners of her mouth turn up like the Joker’s. Once the Joker hit Robin until he died. Once he shot Batgirl so she couldn’t walk, and did bad things to her.

“It’s a special camera,” Dr. Orton is saying. “Ultraviolet. Is it okay if I take some pictures with it?”

Rhi nods.

“Look, I’ll take one of myself first. See?” She rolls up her sleeve.

Rhi understands the difference between Dr. Orton and the Joker. Dr. Orton is good. If she met the Joker, Dr. Orton would know just what to do. She’d fight. She’d win.
