It had not been a good day. Hagen was unable to track Matt Winston down, causing the case to be put on hold. Tim looked up as Brianna walked into his office. She closed the door behind her and sat down.

"What's up?" Tim asked.

"Let's go get dinner."

"No." Tim shook his head. "I've got tons of reports to sign..."

"Yeah. Like you had tons of evidence to log in. I saw you leave after you thought I was gone."

"Brianna, I like you okay but..."

"...but you're married." she said flatly. "It's just dinner. No one will think twice about it."

"My wife will."

"So?"

"So? I'd like to stay a married man, thank you very much." Tim said.

"How come she can flirt with Delko all she wants but you need to stay in this little cage she's made for you?" Brianna asked. Tim laughed and leaned back in his chair.

"Because I know it's nothing between them except joking. You actually try to make a pass at me."

"You don't see what a good thing we could have." Brianna said. Tim shrugged and walked over to the window. Brianna grabbed his arm and turned him around, kissing him deeply. From the stairs, Calleigh watched through the transparent window and gave a small smile, then walked away.

Tim sighed and closed the door behind him.

"I'm home. I didn't see you at the lab so I figured you were home already." he called, walking into the living room. "Hey baby girl."

Isabella was in her playpen, watching an Elmo's World video and chewing on her fingers. Tim heard footsteps behind him and he turned around.

"Hey."

"Hi." Calleigh said shortly. She turned the TV off and lifted Bella out of the playpen. Tim then noticed the bag on her shoulder.

"Where are we going?" he asked.

"We're not going anywhere. I'm going to my mother's."

"Why aren't I going?"

"Right now I really don't want to be anywhere near you." Calleigh said. "Bye."

"Wait, what's going on?" Tim asked, confused.

"I think you know." Calleigh walked into the kitchen and grabbed her keys off the table. She went towards the door and opened it, but Tim slammed it closed and kept his hand against it, not letting her leave.

"I think I don't know. Tell me what's going on."

"I saw you with Brianna okay. I'm not stupid. Now move."

"You weren't even there."

"Oh I wasn't there so it seemed okay and I'd never have to know and look like an idiot while everyone at work knew my husband was screwing the new girl. Well I was there Tim. I was on the stairs. The lab does have windows. Maybe if you wanted some privacy you should've closed the curtains instead of just the door."

"Are you crazy?"

"I guess so because I did marry you and thought that you loved me."

She moved his arm out of the way and walked out. Tim stood there, shock written all over him. He quickly opened the door and ran out to Calleigh's Grand Cherokee.

"Calleigh, get back here. I should at least give you an explanation."

"I don't need one. I saw everything." she said, closing the back door. "I'm leaving. There's food in the fridge. You know how to cook. You have clean clothes. Good bye."

"If you saw everything as you say you did, then you would've seen me push her away."

Calleigh laughed and walked around to the driver's side.

"Don't try changing your story now."

"I'm not changing anything! You just walk out of here with our daughter and leave because you think I'm cheating on you! Why the hell would I want to cheat on you?"

"You're asking the wrong person." Calleigh replied and got into her SUV. She drove off and Tim cursed loudly as he stood there for a couple of seconds. Finally, as it began to rain, Tim walked back into his now lonely house.

The next day, they buried Horatio. As they all stood silently, Tim kept giving Calleigh pleading glances but she just seemed to ignore him. Brianna, on the other hand, kept smiling and batting her eyelashes at him and that didn't help matters much. Once the funeral was done, Tim raced after Calleigh as she walked back towards her car.

"Calleigh! Baby, please wait!" he called, trying to catch up to her. Even in heels, she seemed to move quickly. Tim finally caught up to her and grabbed her hand. "Will you please listen to me?"

"Leave me alone Tim."

"No. Calleigh, I'm sorry but I didn't do anything."

"Yes you did. You hurt me."

"I'm sorry then. But I swear I didn't start anything. She... she jumped me like a cat would a mouse. I had no time to react."

"Why don't you go crawl back to her and try to come up with a better excuse? I'm not falling for anything Tim."

The two of them fought for a few minutes, unaware of someone watching them intently. Calleigh finally yanked her hand out of Tim's grasp and unlocked her door, got into her car and sped off. Tim swallowed back tears and headed towards his Tahoe. He knew how Calleigh felt about Brianna and with Brianna make every advance towards him, it was going to be hard to get back his family.
