Jane thought Susie had the worst timing.
It wasn't like Jane kissed Maura in her office that much - wasn't like they even rounded second in her office - but every time Maura closed the blinds for a little privacy, a few minutes later Susie would knock apologetically, waiting until the door opened to hand over some paperwork. Usually she was followed by Korsak or Frost, sometimes a detective from a different team or another lab tech.
But Jane hated the sound of that distinctive, tentative knock that only Susie gave, because it came with the knowledge that she'd have to stop kissing Maura a moment later. Some days they practically lived at the office, and now that Jane had been brave enough to kiss Maura she wanted to do it as often as she could, anywhere she could. She knew Maura thought it was inappropriate to kiss they way they did at work, but she never actually complained. She never complained about Jane kissing her, because she'd waited just as long as Jane had.
The knock came, and Jane groaned, tucking her shirt in where Maura's reckless hands had tugged it out from her pants.
"Yes, Susie?" Jane asked as sarcastically as she could. The door opened a crack and Susie's head just popped in.
"I got Todd to keep Cavanaugh busy for a few minutes, but he came down here to see you so you'd better make sure you're both presentable."
Jane's jaw dropped and Maura blushed, straightening her skirt and wiping her lipstick from Jane's throat, buttoning up Jane's shirt.
"Thank you, Senior Criminalist Chang," Maura said stiffly, but Jane understood suddenly. That Susie had been - she'd known. And she'd been helping them by not letting anyone else interrupt them. By waiting until Maura opened the door so they could keep what little privacy they had left in this place.
"Yeah, thanks Susie," Jane said, giving her a smile. Susie blushed at Jane using her first name, and Cavanaugh appeared behind her in the doorway as she scampered back to the lab.
Susie didn't have bad timing, Jane realised. Susie had their backs.
