Because ifiknowyouatall noticed that Callen owns a shirt identical to the one Kensi wore in Frozen Lake.
"This stack: done," Deeks said, popping his lips as he filed away a pile of paperwork. "Next stack-" he paused, hearing the familiar banter of the senior agents in his unit. He raised an eyebrow at Sam's morning nagging routine. "To be continued."
"So what you're saying is, you're not going to see her again? Because she's too normal? Come on, G."
"All I'm saying is, she deserves somebody that isn't always lying to her," Callen explained, turning the corner into the bullpen with his partner. "Morning Deeks."
"What's up Deeks," Sam greeted him, clapping him on the back.
"Gooood morn-"Deeks stopped speaking mid-word, feeling the color drain out of his face when he looked at his team leader. "Is this a joke?" he asked, pointing to Callen's shirt.
Sam narrowed his eyes, looking back and forth between his team members. Callen looked at his gray button down shirt, perplexed, pulling it away from his chest. "Am I missing something?"
Deeks cleared his throat nervously, looking back down at his paperwork. "It's nothing. I just…my mind is playing tricks on me, I guess. So, this teacher of yours, she's too good for you, yeah?"
"No," Sam answered for his partner. "G is, ironically, just not comfortable living a lie. Apparently."
"Yeah." Deeks glanced suspiciously up at Callen's shirt again. "Yeah no. I agree."
"Thank you, Deeks." Callen shot a smug look at his partner.
Pulling his phone out of his pocket, Deeks excused himself from the bullpen and walked over to the window by their lockers. He pulled up his photo album on his phone and started flipping through it, trying to find the last set of pictures he took with Kensi before she left for Afghanistan. Stopping at a photo of the team playing basketball in the gym, he focused in on the two of them. His arm was wrapped around her shoulder and they both looked happy, not knowing in short time the trials they were going to face. Sneaking a peak back at Callen for a second, he compared the shirt he was wearing with the shirt Kensi was wearing in the photo. They were almost identical.
Smiling sadly, he typed a text message to his partner:
"Hey Kens. I must really miss you cause I swore Callen came to work today in one of your shirts. I know it's not possible cause you've burned that damn thing by now, right? Be safe."
Unbeknownst to him, he was being watched closely by Sam and Callen. "What do you think he's doing?" Sam asked.
Callen pursed his lips. "Struggling to live his lie, if I had to guess. He's not very good at hiding it." He turned to look at his partner. "And if he thinks it's hard now, wait till she gets back."
Nodding, Sam turned away from Deeks and started walking up to Ops. "Trust me, I know." He paused on the stairs, waiting for his partner. "What is the deal with your shirt anyway, man?"
Callen shrugged. "I have no idea. I stole it from the dressing area like, 2 years ago."
Sam shook his head and rolled his eyes. "That is sad, G. That is really sad."
"Is it ugly?"
"Yes."
"Think I should return it?"
"I think you should put it out of it's misery."
