Jubilee's doodle made Shiro smile a bit, "You should put that in an envelope and give it to them on their wedding day." As he sort of adjusted his legs so that the smaller woman would better lean against him (it wasn't that they'd done this often but Shiro did know how to be an older brother and in the past, he and his sister reached a compromise of positions and spaces whenever they were sharing a couch), he proceeded with his responding doodle, tracing long lines, mostly curvic ones.
"Ororo's dress," he repeated to himself as he folded his left hand's fingers and stood the thumb up to copy it (oh how glorious, the feeling of moving the left thumb is), "That's going to be difficult now, I think...in any case, I'm pretty sure I'm on the safe side." Pen was capped and doodle handed to Jubilee. "My formal suit's dark olive-ish; I've gotten it dry cleaned for the wedding. I'm surprised you wouldn't wear something ass-bearing, though, not that you have much to bear." He did not mean any serious offense by it, he swears.
