He doesn't even hear Rarity coming, let alone have time to hide the guitar. But for some reason he tries, shoving the guitar under the covers on his bed. It doesn't necessarily work...since the shoulder strap is kind of hanging out, and she knows damn well what he was doing already.

If Rarity was a mom, she would be the best mom.

"Aw, c'mon, what else am I supposed to do? I can't sleep!" He throws his arms up rather dramatically, giving her one of those looks that only a moody teenager can supply. "I haven't been able to since!" Since...yeah.

There's a pause before he continues. "We lost our drummer. We can't lose a lead guitar either. There's gotta be a way I can play with this. I'm gonna find a way whether the doc said to or not."
