To say Oliver's emotions towards his mother had flipped in the past 12 hours would be an understatement. When he'd left the mansion this morning, he'd been disgusted and furious with her. But ever since he gotten the phone call from Walter saying that his mother had been kidnapped, now all he felt was fear and concern about losing his mom all over again. He'd barely managed to get past Slade killing his mom, but now if he lost her again, this time with her thinking he hated her, he'd never forgive himself.

That was why he currently found himself standing in the mansion with his sister and stepfather, along with Detectives Lance and Hilton.

"How did the kidnapper even get in. I thought this place had one of the most advanced and expensive security systems in the city." Thea said.

"She's right. Alarm sensors on every door and window, surveillance cameras, security patrols, it doesn't seem possible that someone was able to get through this undetected." Oliver said, knowing the mansion's security protocols too well, not only from his time as a vigilante, but considering how many times the cameras had busted him, usually with Laurel or Tommy, sneaking either in or out after curfew.

"Whoever did this was a pro and they've obviously been planning for awhile, since they managed to always be in the blind spots of the cameras and it was like they knew all the alarm codes and the guards schedule." Quentin said.

"Suggesting it might've been an inside job. No one but us and the security company we hired for the mansion's security could know all the information." Oliver said.

"Just to be safe, go through the list of people who know any of the information needed to pull this off." Hilton said.

"Me, Walter, Thea, mom, Laurel." Oliver said.

"Wait, Laurel?" Quentin asked.

"You're forgetting how much she spent here even before we were dating. My parents told her the codes because they trusted her and after we started dating, we spent a lot of time looking for blind spots in the cameras and I think that's all you want to hear." Oliver said and Quentin nodded.

"Also, Tommy, but he's out of the country last I heard." Thea said and Oliver nodded.

"And the security company." Oliver said.

"Actually, my boyfriend Roy knows the alarm codes to, but he'd never help anyone, since abducting my mother is a breakup move." Thea said.

"Okay thank you." Quentin said.

"You'll find her right?" Thea asked.

"We'll do our best." Quentin said as Walter showed him and the other cops out.

"We're not just gonna let the police handle this are we. I mean, I'm mad at mom for what she did to our sister to, but still." Thea said said, since Oliver had told the rest of the team about Emiko shortly before they'd gotten the call that their mother was missing.

"Absolutely. Mom may have made mistakes, but she doesn't deserve to die." Oliver said.

"Maybe we should go over the security footage again. See if there's anything the police missed." Thea said.

"Already texted Winn to do just that. This one's personal. Besides, I have a feeling it's somehow connected to our latest problem." Oliver said.

"Why would Church come after us through mom. He has no idea who we are." Thea said.

"Doesn't matter. Something tells me that this kidnapping is somehow related to him and figuring that out is just as important as finding mom, since we need to know if our identities are compromised, since if they are, that'll just put not only mom, but also Walter and anyone else we care about at risk." Oliver said and Thea nodded.

"Any luck?" Laurel asked Oliver when he and Thea entered the base.

"No, apparently the kidnapper managed to stay in the camera's blind spots." Oliver said.

"I didn't realize there were enough of those. After all, we both know how tight the security is on the mansion." Laurel said.

"Actually, I did a little tampering." Winn said.

"What, why?" Thea asked angrily.

"Here's what the actual footage was." Winn said as he played it for them.

"That would've not only revealed Thea's true parentage, but also possibly out her as Frostbite." Oliver said and Winn nodded.

"So I hacked the footage and modified it so that while the police could still get intel from it, it wouldn't give away anything that compromises our operations." Winn said.

"So apparently my birth father is still alive and it looks like he has the same powers as me." Thea said.

"And he also knows about you, which means that he probably knows that you're Frostbite. Guess I was wrong about Church being involved in this." Oliver said.

"Still, we need to find him and Moira quickly." Laurel said.

"I'm already on it." Winn said as he pulled up an algorithm.

"What's that?" Thea asked.

"It's algorithm I wrote to track your UV cold signature, since your powers give a unique reading and if your father has the same powers as you." Winn said.

"We should be able to track him the same way. Nice." Oliver said.

"Yep. I should get a location back quickly, assuming that his signature isn't shielded." Winn said.

"Let us know when you get a hit." Thea said and Winn nodded.
