S4: Ep 42 Dee feels she's the only one to care that Patch has gone missing. Salene's priority is fixing up the steady stream of kids injured in the Color Wars. Dee points out that Patch is the only one who knows what he's doing.
When an injured girl comes in, a Red, Dee recognizes her as a previous patient who had promised to stay out of the street fights. Dee refuses to treat her, hoping to force Salene to change her priorities.
Salene talks to her shortly after when Dee's a little calmer. She wonders if Dee has feelings for Patch that are coloring her judgment. Dee denies it, probably doesn't even know it, but maybe Sal. touched a nerve?
Anyway, Dee's eye design appears to have changed between scenes. The lines and the colors of the sparkly butterflies.
