She was sitting on the stool at the opposite of her desk. Her head was resting lazily on propped up hand, they way it does sometimes when she is deep in thought. He couldn't help but follow the gaze of her eye, just wanting to be able to come along. A loose strand of blonde hair shifted onto her cheek, and he wanted so desperately to brush it back, secure it in its proper place behind her ear. That type of action would give him away, though, and he knew that he couldn't let that happen.
SG-1 had just gotten back from a particularly difficult mission just a few hours prior. Daniel was actually still lying down in the infirmary, nursing a wound from a staff blast that just niched the outer edge of his leg. The nature of their work wasn't serene, wasn't beautiful. It bore the type of details that should never be told. He knew that deep down, this was weighing her down. Don't misunderstand, now. He knows how much her work means to her. This is what she lives for. If possible, she would spend every last hour in her lab or off-world, but that didn't mean that it didn't weigh her down none-the-less. So many times, he wanted to venture into those dark corners of her mind, hold her close, and kiss away all her fears.
He knew that was impossible. There are some lines that neither of them are willing to cross. However, that didn't stop him from enjoying just watching her in her simplicity. He knew that what he was doing was probably wrong, watching her in secret, but somehow he knew that she wouldn't have minded even if she had known. Heck, maybe some day, in the distant future, he would tell her about it, and they would laugh.
In stealth, he abandons his place by her desk and leaves her lab behind. As a big smile spread across his face, one that he knew nobody would ever see, he couldn't help but think about how there were benefits to being invisible.
the end.
