Stiles was half tempted to just have Scott leave the room. Though he wouldn't do that because he needed his best friend there. However, telling him not to panic was really counter productive because he's going to panic. He bites his bottom lip and gives a slight nod," Yeah, okay." It didn't stop his mind from reeling though. Hadn't Melissa also told Scott not to let Stiles pull anything? Sitting up is bound to do that.
