Elizabeth bursts in and tells Mark he's needed in the hallway. "Ella has something to tell you," she announces. And so Mark just ditches the patient and flees. Good thing Chen is there.
In Trauma Green, gruff coffee vendor Charlie is being treated by Weaver and, partly, Elizabeth, who is distracted by watching Mark cuddle Ella. Haleh enters to alert Weaver that Renee's mother has arrived; Weaver quasi-calmly asks whether there's been word about the firefighters. There hasn't. Haleh leaves. Elizabeth smiles at her husband and daughter, happy that they get along so that she won't have to spend all her time with either one of them.
Weaver finds Renee's mother hovering at the girl's bedside. Mrs. Renee is grieving, and totally shocked. Kerry gently says that they managed to stabilize Renee for now, but that they must wait for signs of a full recovery. Tearfully, Mrs. Renee says she heard about Diana; when she learns that Diana died, she hangs her head with a moan. Weaver considers this. "Was Renee having problems at school?" she asks carefully. "Was she depressed, or showing signs of...." Mrs. Carlson's head pops up defensively. "Why are you asking this?" she wails. Weaver backs off, swearing they're just trying to make sense of tragedy, except that she sounds accusatory and it's clearly not the right time to implicate Renee to her sobbing mother. Nice work with the discretion, there, Kerry. But I understand -- she's just worried that all lesbians are teeming with murderous rage. She's not trying to understand the attack, she's trying to understand herself. Uh huh. Mrs. Carlson makes a strange comment about why "everyone" is asking all these questions, and when she finds out Renee did not have any defensive wounds as Diana did, she stands up in a rage of tears and eyeliner. "My daughter didn't hurt her friend," shrieks Mrs. Carlson. "And she certainly did not do this to herself. There must be a maniac out there." Weaver looks on pityingly as Mrs. Carlson plops back down and murmurs repeatedly that Renee will sort all this out when she wakes up.
