A/N: Change three, visiting the crime scene. Because Anna might be a Hunter, she's also an FBI agent.

Anna kept her mouth shut until they reached the hotel that night. Since they were using her card, she managed to strong arm Dean into accepting a room at the Holiday Inn as opposed to whatever hole-in-the-wall he happened to find. From the look Sam shot her, he was just as relieved as she was that he agreed with little trouble.

She followed the boys into their hotel room and kicked the door shut, "You are not breaking into the crime scene," she announced when Dean turned to look at her.

"What?" Dean demanded.

"I know how these things usually work," Anna replied, "and there are any number of crimes I'll overlook or assist you in committing, but breaking into a crime scene is *not* one of them. I'm planning on going over there myself, just to look around the outside, and I'll take you along if you promise not to try to break in when my back is turned." She crossed her arms and glared at her brother, "Look, Dean, if this weren't an active police investigation, I'd say go for it, and if I weren't in the FBI I'd be first in line. The thing is, even if we could find proof that Zack is innocent, there's no way it could legally be used afterwards. We have to preserve the chain of evidence to get Zack free."

"She's right," Sam said, "and I hate to say it, man but we have to do this right."

"Besides," Anna said, "there is one question we can answer by looking at the outside of the house."

"What question is that?" Dean asked.

"If Zack's doppelganger waltzed in the front door, but was gone by the time Zack called 9-1-1, how did it get out?" Anna replied. From the look on Dean's face, that fact had not occurred to him, it was times like this that Anna wondered if all men were lacking in common sense.

Her phone rang and Anna pulled it out, "Excuse me," she told the boys and opened the door, "I need to take this." She let the door fall closed behind her as she answered the call, "Hi Hotch," she said cheerfully.

"Is there a specific reason I should have gotten a call from the St Louis PD asking why an FBI agent was nosing about their case?" Hotch said.

"The cops called," Anna repeated, "wow that was fast and I thought it would be the lawyers who called. I thought I'd manage to call you first though." She let herself into her own room and dropped her bag on the bed.

"What's going on, Anna?" Hotch asked.

"A friend of Sam's has been accused of murder," Anna replied, "His sister says he was with her at the time of death, but a security camera shows him entering the house shortly before the woman died. She asked for help, I listened to what she had to say. I told her from the beginning I couldn't officially investigate since I'm on medical leave." She paused in the act of kicking off her shoes, "What did you tell them? What did they tell you? Hotch, I swear, I wasn't really trying to get involved. Unless this murderer kills again, or some astonishing evidence comes to light, the kid looks guilty as sin. I'm making a few motions to reassure the sister, maybe look at the outside of the house, but I'm not getting involved. I'm more concerned that Dean will do something stupid to impress the pretty girl."

"Anna, we agreed to this medical leave because I didn't want to suspend you," Hotch said, "that means you aren't allowed to investigate."

"I'm not," Anna protested. "The most I intend to do is call an anonymous tip if I see something. I have other reasons for being in St. Louis."

A knock on the door that sounded suspiciously like 'Pop Goes the Weasel' had Anna frowning. "I told the cops you were an agent on leave and shouldn't get involved."

"Great," Anna said, "perfect." She sighed, "Look, Becky's a nice girl and Zack's a good kid, but I don't want to be involved. I just can't wave a magic wand and not be an FBI agent for a while as much as I'd wish too. My brothers are proud of me and want to brag. If it helps, while I have my badge, it's buried in the bottom of my backpack and I'm going to play the 'further investigation' card at the earliest opportunity."

The knocking on the door switched to what Anna identified as 'We Will Rock You'. "Just so long as you remember you aren't invited into this case even if the team is." Hotch said.

"Right," Anna replied and took her wallet out, "I promise." She glared at the door, "I'm sorry, my brothers are trying to beat the door down. I need to go, but I promise. I will not investigate this story any further."

"Right," Hotch said, "please do."

"Talk to you later boss," Anna said as she realized the tune had switched to Iron Man. She hung up the phone and yanked the door open to glare at her brothers. "I was talking to my boss," she snapped. "Apparently the cops called to ask why I'm asking questions about Zack's case."

"What does that mean for us?" Dean asked.

"It means that if you go and break into that crime scene, I'm taking the Impala back to DC with me. " Anna replied, "I just swore up, down and sideways that I wasn't going to investigate this case and that means I can't play off getting caught trespassing on a crime scene in St. Louis."

"Don't you touch my baby," Dean said.

"Don't you touch that crime scene," Anna retorted, "Deal?"

"Deal," Dean replied.

"Why do I always end up feeling like the normal one?" Sam muttered.
