Upon Wills first words Isabella could instantly pick out something was slightly wrong in his tone -even if no one else around seemed to notice anything at all. It was a subtle shift. Either they were rather unobservant or she was just good at reading people, because the fake yawn was even worse followed by the smooth white lie. She looked up in slight surprise to him, and meeting his eyes it was clear in her expression so he would know she knew something was up but not exactly what it was.
"Yeah sure man, get a good rest because you're going to need it for tomorrow when I take you down." With the hand motions to add emphasis, he turned his attention back to telling Isabella and the Hermes girl some sort of a story. She didn't really know, because she wasn't listening -her mind in other places watching Will leave and wondering if she should say something. Probably not, it was his own business what was bugging the guy. And if he wanted her to know, he would have brought up what was bugging him.
Then again, Isabella did have a stubbornly persistent attitude that often got in the way of actual logical thinking.
"Hey, what cabin number is Hermes?" She asked lightly, and upon recieving the answer from the Hermes girl from before gave a thankful nod. "Great, thanks. I think I can find my way back on my own, I would rather go now and settle in ahead of time, ya know?" With that she got up, brushing off the protest Kaidan gave with a light smile and reassurance she wanted him to enjoy the rest of his night. Only after a hug did she finally manage to get away -Isabella was rather good at slipping out of places- but it took her almost no time at all to catch up with Will.
In the direction they were going, cabin 13 was before cabin 3 so she would be breaking off before him. "That was a pretty bad fake yawn." The girl said lightly, walking with her hands in her pockets once she had caught up. It was no lie, she was fast. Although Isabella didn't ask him what was wrong, still thinking if Will wanted to talk he would. Rather, she just walked with him. "You have to press your tongue down when you do, or it just looks like your going to sneeze."
