Mac paced to and from his office. It's hard to be him --- Mac Taylor --- and separate his professional and personal feelings towards a case, and separate what the evidence is pointing out and his judgment for a person who is clearly a scum of the universe.

Stella walked in, and in her hand is a case folder. "You're going to mess up your carpet that way, Mac" she said.

Mac sat on his chair. "I hate it when I have good evidence that doesn't seem to be enough"

"Sonny Sassone?" Stella said.

"There's no doubt that he beat up Danny" Mac said "but we don't have evidence to prove that he pumped him with morphine and stuck him in that tub filled with water"

"Maybe he didn't do it" Stella answered.

"Knock knock" Lindsay walked in.

"You're still in the same clothes you were wearing yesterday" Stella said.

"She hasn't gone home" Mac answered. "How's Danny?"

"Still unconscious" Lindsay answered while wringing her fingers. "It's been eighteen hours, Mac."

"What are you saying?" Mac turned back to Stella "It's not Sonny Sassone?"

"Blood on the carpet is Sonny's but the blood on the couch isn't. It's um…. It's female." Stella said.

Stella and Mac turned to Lindsay. "I've only been to Danny's once" Lindsay answered. "I don't remember bleeding."

"It's um…. It's not you. It's someone else." Stella said.

Lindsay looked away.

"Michelle Vernon" Stella answered.

"She's on CODIS?" Mac asked.

"Every medical practitioner is on CODIS. She's a psychiatrist." Stella said. "She lives right across Danny."

"She's a doctor. Has access to morphine and syringes." Mac answered.

"What do you think? An angry ex-girlfriend? She found him in his apartment bloodied and beaten up? Saw an opportunity?" Stella answered.

"I, um…." Lindsay started.

Mac and Stella turned to her, becoming aware of how this information must have hit her.

"I'm going home to take a bath. Change my clothes" Lindsay said as she turned to leave.

"Lindsay, I was just speculating…" Stella said.

"I just, um…." Lindsay answered. "I just want to know who did this to him"
