This is an absolutely terrible idea, no questions about it, && Spencer cannot believe he'd let Oliver drag him down to the skate park. He should have told him no, shut this idea down immediately with a quick recitation of skateboarding-related injury statistics; it was more likely that Oliver would get hurt than that this would go well in any way shape or form. The problem is, Spencer's been weak to Oliver practically since they'd met && would fold instantly to anything Oliver wanted, all he had to do was ask with that sweet face of his && Spencer would be gone, && he's pretty sure Oliver knows it.
So he watches Oliver skate, at first with his arms crossed && a look that was a barely disguised mix of anxiety && disapproval. He's so certain that Oliver is going to slip && crack his skull open && then where would Spencer be?? Having to explain to Mrs. Wolf that, against his better judgment, he'd let Oliver do something dangerous && now he's in the ER getting his skull fused back together, that's where.
To Oliver's credit, though, he seems to be doing okay. Enough for Spencer to stop drumming his fingers anxiously against his bicep && uncross his arms altogether. After a moment, he sits on the lip of the bowl to watch Oliver instead; though he's still anxious, he's less convinced Oliver is going to slip && crack his head against the concrete.
&& then Oliver slips && cracks his head against the concrete.
Okay, maybe he doesn't exactly crack his head open, judging by the lack of any immediate blood splatter. But the sound his body makes when it hits the concrete && the way his head bounces against the ramp as gravity pulls him down is enough to make Spencer cry out. He's on his feet in an instant, scrambling down the inside of the ramp to kneel beside Oliver. This was a horrible idea, he knew it, this was a horrible idea && Oliver's hurt && he's a terrible boyfriend, he should have stood firm on this being a stupid idea && insisted they stay home && watch Doctor Who for the hundredth time instead.
❛❛ Oliver?! ❜❜ His panic is clear in his tone as he surveys the other boy; no obvious injuries that he can see, though he's sure the other boy will be covered in bruises by the morning. The lack of blood is a good sign, at least, but he can see that Oliver's eyes are unfocused && he's certain the boy has at least a mild concussion. So he raises his left hand over Oliver's face && holds up 3 fingers, asks Oliver to tell him how many that is.
He does not get the answer he hopes for. ❛❛ You are not fine, Oliver, you almost certainly have a concussion — don't try to sit up yet!! ❜❜ His voice goes embarrassingly high at the end, almost sounding hysterical, as he pushes at Oliver's shoulders to keep him laid out on the concrete. He does show the boy a little mercy, though, maneuvering Oliver so his head && shoulders are leaned back against Spencer's lap instead of the hard concrete of the bowl.
❛❛ Just — Just lay there, for a second. ❜❜ Spencer runs a hand through his hair. He takes a deep breath, then lets it out slowly; Oliver is ( relatively ) fine, there's no need to panic. Treating a concussion is easy && he'll likely be just fine in a couple of days. It could have been a lot worse.
❛❛ We should get you to the emergency room, ❜❜ he says finally after a few moments of thought. ❛❛ Do you think you can stand?? I can drive you there. ❜❜
