When Ty arrived at roll call, he couldn't get Alex's words out of his head.

'Maybe I should take this as a sign or something. Someone or something kept Alex safe so we could have a shot at a life together. What else could it be, it could have just as easily been here in there,' he mused.

Faith and Sully quickly brought him back to reality. They told him about the killer that was still on the loose and a puzzled look crossed his face.

"I thought he shot himself?" he asked, perplexed.

"We found out there were two of them." Faith replied. "One only sustained minor injuries. The paramedics must have triaged him and released him, not knowing who he was." None of them were prepared to admit it, but the cops were glad to have someone to catch and bring to justice. Suicide didn't seem like an adequate punishment for nearly killing two of the people they all loved. They left the building heading for the squad cars with a renewed sense of purpose. Faith left with a temporary partner while Sully and Ty prepared to hit the streets.

"Its amazing that the other killer was right there and no one noticed. The paramedics probably even triaged him and sent him on his way." Sully grumbled.

"It was total chaos Sully, you saw it. No one knew whether they were coming or going, much less who else was," the young officer offered insight beyond his years.

"I guess you're right Davis." They drove around the corner in silence. As if a light bulb had appeared over Sully's head, he suddenly stopped the car and said,

"I can't help but think that Doc, Carlos or Alex had him right there, maybe if we describe him they'll remember." Sully offered

"Well, if we catch him, they can I.D. him as being at the scene at least, but there were so many people, I doubt they'll remember. Alex never mentioned anyone in particular." Ty momentarily dampened Sully's newfound energy, but the veteran officer said,

"That's because she wouldn't have known who he was at the time Davis, of course he wouldn't stand out, and especially not when she was worried about Kim and Bosco. We should at least ask; it can't do any harm."

"It might" Ty mumbled, thinking to himself 'I know her, she'll feel awful if she treated and released a killer, regardless of the fact that she couldn't have known who he was at the time.'

At the firehouse, Doc and Carlos sat eating and talking in hushed tones when Alex walked up the stairs.

"Alex, what are you doing here? You're more than entitled to some time off right now." Doc offered gently.

"I can't sit around at home, there are people out there who need saving. If I can't help Bosco and Kim, I can help someone else." She replied courageously. "What were you guys talking about anyway?"

"It seems like there's another killer out there." Carlos blurted. Doc smacked him on the back of his head.

"Way to go Carlos" he hissed.

"What?" Carlos exclaimed, much louder than the obviously delicate situation demanded. "She's gonna find out sooner or later anyway."

"What do you mean? I'm not any more upset than anyone else about a second killer."

"We figured out that you must have…" Carlos started again, when Doc kicked him under the table. "Ow! Ok already! Geez Doc"

"You really are the least sensitive person I have ever met Nieto," was all Doc offered in response.

"Doc? What's going on? What did you stop Carlos from saying?" she asked timidly. Doc sighed and then launched into as kind an explanation as he could muster,

"Alex, Sully and Ty just left about ten minutes ago. They left a description of the second killer, who they said must have been treated and released at the scene. Neither of us recognized him. That means you must have treated him…"

"And let him get away" Alex finished as she slumped into a chair.

"No, look, Taylor, we knew you would feel like that, that's why we didn't tell you." Doc tried to comfort her, "you couldn't have known who he was. You did your job and did it well. You treated his injuries and moved on to other patients. You didn't do anything wrong Alex, got it?"

"I guess you're right" she mumbled as her mind screamed 'How could you let him go? He blew up your partner! You should have known; you should have seen a sign! Now there's a killer out there and you made him better.'

"What did he look like?" she sighed, wanting to see if she could at least remember who he was. Doc and Carlos gave her the composite sketch the officers had left with them. She sat desperately trying to recall the face and the treatment she'd provided him, but it seemed that the harder she tried, the harder it was to remember anything about any of the patients she'd treated that day.
