Catherine hadn't been back to Nick and wasn't with Grissom when he went back, and he immediately worried. Not hesitating, he unlatched his cell from his belt and hit the number 2 on speed dial for Catherine, tapping his fingers impatiently on the table. "Willows."
"Catherine! Where the hell are you?!"
"Nick..."
"Are you alright?"
"Nick..."
"Are you with anybody?"
"Nick..."
"Well, you're obviously fine! This thing is serious, Catherine, and I don't want anything to happen!"
"HEY...I'm sorry."
"Sorry? Sorry?! I've been waiting and here you are all fine and dandy while I'm worrying my ass off about you!"
"I'm sorry!"
"Where are you? I'm going wherever you're going."
"WHAT? No, don't you dare. I'm fine-Sara's with me."
"Oh, so you head out with Sara for lunch or something and you don't even decide to tell me! Catherine, I just don't want anything to happen to you!"
"Nick, just sort the damn evidence. I'll be back in a bit with some lunch!" With that he heard a click of the phone telling him she had hung up on him. Alright, he had sort of flipped but he was worried, and wasn't really upset with her, just upset generally. Rubbing his forehead, he looked down.
Nick sighed, staring at all the evidence and pure relief flooded through him. Gazing over the evidence, he picked up the two evidence bags with the notes, and on Catherine's persistence, that awful photo. Walking fast down to the labs he spotted one of the document lab guys and called out to him. "Hey Charles!" The young red head turned and nodded, telling him to go on. "I have two letters I need you to analyze. When you're done, bring 'em straight to me." Charles nodded before walking off down the corridor.
Setting the bag with the picture face down on a corner of the light table, he found the large, thick envelope of pictures the labs had developed for him already since he dropped it off first thing back. Spreading them out on the light table, he set off sorting the evidence and recording what tests were needed for each when David walked in.
"Hey, Nick, I've got your vics ready for further processing. Then Doc'll take care of them." Nick nodded, checked his watch and scrolled a note for Catherine and left it on the table which read, 'Catherine, went to go process vics further. Come find me if I'm not back when you return. Nick' Taking his kit with him, he threw a coat on over his shirt and jeans, placed gloves on his hands, and entered the morgue.
