Poo often was the last of the four to fall asleep, leaving him to his thoughts once again as he glanced at their sleeping faces. Ness and Paula slept together in the same bed, their backs always seeming to end up touching by the time morning came, and Jeff, when he wasn't working through the night fixing one thing or another, slept beside him, and the prince had to be careful not to move too much lest he wake him, the scientist's son a light sleeper.
Whenever Jeff was up working through the night, Poo accompanied him in his wakefulness, watching Jeff quietly and without comment. At first, he would look away whenever the blonde's emerald gaze wandered near his own, as the prince had learned that being watched made Jeff nervous, though after a while he seemed to grow used to it and even met the prince's gaze with a little nod whenever Poo was caught observing. One thing that always stayed the same was that when Jeff was done with his current object of interest, the two of them would converse in a low voice as not to wake Ness and Paula, though Jeff assured him that the pair could sleep through the end of the world without waking.
It was through this nightly ritual, done once or twice a week, that Jeff became the one Poo was most familiar with, and vice versa. The prince learned that Jeff was a bit estranged from his parents, went to a prestigious boarding school (by obligation rather than choice, he had added hesitantly) and had a best friend named Tony who he missed on a fairly regular basis. Jeff, in return, had gained more knowledge about him than most had the privilege to know—deep down, Poo was a pacifist, something he couldn't reveal back home without disappointment from his master, who had given seemingly endless time to train him into a powerful warrior, and being a prince had made him very popular with the ladies back home—the latter information invoking a quiet laugh shared between the two.
Later, in the time after they had disbanded, he would think back to those times and, after he had thought of Ness, of Paula, of them as a group, and then—for just a little bit longer—he would think of Jeff, wondering if he ever got to reunite with his best friend, and silently missing those old times where the weight of Giygas was temporarily discarded in favor of those short late-night talks.
