Maes confusion following that came in many stages. The first was the initial feeling of the arm around him. Even his experience working in Investigations wasn't required for him to puzzle out that he'd gotten drunk, hence the terrible hangover, and slept with someone. He'd done it once or twice before, swearing that time to be the last, but it seemed as if he'd erred once again. He felt sorry for whoever the broad was and just hoped that there wouldn't be too much embarrassment whenever she decided to come to -- and that they'd used protection, at least.
The next stage of confusion came when he felt the strength and muscle tone in the arm. Drunk or not, Maes tended to only have one preference when it came to women, and weightlifting was not a point on his check list -- not that he minded muscles on a woman, however there was a limit.
He got his mind back on track, having digressed from the point, and Stage Three ensued. Looking down at the arm not only reminded him to make sure he could find his glasses, but also fuelled his confusion. Indeed, it was as muscular as he had imagined, however it was also a lot more hirsute than he had expected. The usually bespectacled man used this knowledge and pondered on what the person looked like briefly; the hair on the arm was fair, leading Maes to envision the person as blonde. A blonde body-building woman...Heaven forbid it was one of Armstrong's sister's.
It finally occurred to Maes to look at the face of the person with which he slept. Starting at the fingers, he slowly scanned his eyes along the arm, past the wrist, past the elbow, past the forearm, past the shoulder...and it was then that Stage Four left him the most confused. He had to blink. He had to rub his eyes. He had to screw his eyes shut, turn his head away, shake it then reopen his eyes, but, despite doing all of this, he was still pretty sure he saw Second Lieutenant Jean Havoc beside him in the bed...and the increase in his nausea and headache from shaking his head was what made him think he wasn't asleep; that he was pretty sure of.
But then why the hell was he in a bed beside his best friend's subordinate? He then peaked under the blanket and turned as white as the very sheets on which he lay.
And why were they both stark naked?
