Summer just stands there, in the rowan gap, arms wrapped around Helios, looking slightly bemused. She waits patiently for the laughter to subside again, at least to the point where she can be heard. Then, “I can call a cab,” she says mildly.
It’s almost certainly one of those injokes that would lose greatly in the retelling. But that’s fine; she just wants to get Helios back home where he can run off and sulk properly at the way he’s been mistreated (his concept, not hers). She buries her nose in his fur and watches the two boys over his ears, patiently waiting.
Eventually, the boys get themselves under control. Stiles straightens up, managing to hold himself on his own two feet again, and uses one hand to wipe tears from his eyes while the other stays wrapped around his middle, like maybe he needs the support.
“Are you sure?” He manages to speak a few moments later, expression suspended between concern and residual amusement. “It’s not a big deal, I could drive you guys, I mean I’m right here and I don’t charge fare.”
If Stiles had bothered to actually examine the expression on her face, she wouldn’t’ve needed to ask the question; it’s clear she’s teasing lightly, reminding him she’s here and trying to be unobtrusive about it. So she simply says, “I only didn’t want to interrupt your time with Scott. Whenever you’re ready.” The motion might be a little bit pointed when she sits down in one of the chairs and bends her head over Helios’.
