Against Izaya's own mental behest, he passes out before Celty arrives. Shizuo, trying his damnedest to ignore the brunet's presence, doesn't immediately notice until Izaya slumps further against the brick wall.
"Shit," the blond curses, jolting forward to nudge Izaya's foot with his own. "Oi, I'm not gonna be a witness to your murder!"
When Izaya remains silent, Shizuo runs a hand through his hair with a hiss before crouching down in front of the informant. Fixating his eyes on the brunet's still chest, he focuses his hearing. It's difficult to drown out the typical noises of the city, even while tucked in an alley in the dead of night, and the more he tries to listen for specific noises, the more he hears televisions from the apartments nearby and the roaring cars and clicking heels of shoes going about their business a street over. But Izaya's heartbeat is there, albeit faintly, along with his almost silent breathing.
Shizuo relaxes, tipping back on his heels and letting gravity sit his ass down on the pavement. He goes back to idly smoking while awaiting his friend's arrival.
His eyes trace over Izaya's injuries with nothing else to occupy his mind. The bite to his shoulder doesn't seem intense, the bastard might get away with a few stitches and a bandage, but his bony wrist has been torn in to and snapped for sure. The blood in the air no longer smells fresh, although still pungent. Izaya's probably got a few gods to thank when he wakes up if Shizuo is right and his artery wasn't nicked.
Shizuo's nose wrinkles, his cigarette doing very little to blur out the scent of blood and other Weres and, worst of all, Izaya. The flea fucking reeks, his body drenched with sweat and matting his hair to his face. While Shizuo had picked up on the scent of other Weres in his territory first, it was near impossible to miss the scent of their target, Shizuo's familiarity with the brunet making it all the easier to track the rogue gang down.
Shooter whinnies from two blocks away, cueing the blond to stand back up and walk to the end of the alley to make sure Celty doesn't pass them by. As the dullahan's ride roars towards their location, Shizuo softly curses his lack of a proper shirt. Wearing only the vest makes him look ridiculous, but his friend has seen far worse.
"[Are you alright?]" Celty types out once she pulls up to the curb.
"Yeah, but you're never gonna guess who ain't."
Celty's helmet cocks as she gets up and he leads her into the pitch black alley.
Shinra's at the door, in his pajamas, before the doorbell even finishes ringing. "Shizuo! What did you drag my love out into the middle of the night fo- Izaya?!"
"Shut the hell up and just take him," the blond shouts, holding out the bloody young man in his arms.
Shinra freezes, holding up his hands in surrender and gesturing towards the backroom where his medical supplies are located. "That looks pretty bad, but I'm guessing that it's not from you?"
Shizuo growls and Shinra takes two awkward steps back and out of his way, having to slink around the blond to open the backroom door and keep it from being kicked open when Shizuo's foot rears up.
"Just put him on the table and tell me what happened." Shinra casually says while skittering around the room for his various supplies.
After lowering Izaya to the examination table, Shizuo pulls back as if fearing being burnt. He grimaces at the blood staining his arms and chest, the invisible scent of the brunt's sweat clinging to his skin more intensely than the drying copper fluid. Shinra snaps on a pair of surgical gloves after laying out his tools on the metal tray by the table.
"Dunno," Shizuo says, swiping some of the towels by the sink to wipe at his body. "I was trying to enjoy the night and then I smelt six of 'em and this bastard running, so I went to chase 'em out. Izaya was being attacked when I got there."
Shinra hums in acknowledgment, cutting through the brunet's clothes to examine his wounds better. He whistles once Izaya's shoulder is exposed, the deep indents digging through his skin and exposing some of the muscle. The skin around the entrance indents are torn, indicating that Izaya had been dragged slightly by his shoulder before release.
"It's not fatal and, if Izaya is lucky and doesn't stress it, his shoulder should recover fine." Shinra informs despite Shizuo never asking about the brunet's injuries, beginning to clean the wound carefully for the antibiotic and bandage. He turns around to dispose of his bloodied wipes and fix Shizuo with a stare like that of a parent talking down to their child. "That means no chasing, Shizuo-kun."
The blond's eyes narrow, opening his mouth to bare his teeth and retort when Celty pats his shoulder. "[Do you know why they attacked Izaya?]"
Shizuo exhales and inhales, swallowing his threat to shake his head. "Just that he'd make the fourth in… Two, maybe three, months?"
"Everyone's on edge because of those dirt-bags," he supplies as Shinra continues treating Izaya's shoulder. "Umezaki even approached me about helping to 'take care' of it."
Shizuo's eyebrows downturn as his nose crinkles with annoyance. Turning down the kind older gentleman's request hadn't made him feel too good then and certainly only worse now. It only figures that Izaya would force him in to action. Shizuo just wanted his peace and to be left alone. None of the other Weres were stupid enough to bring shit into his district and he had foolishly presumed that whatever the rogues were up to wasn't going to spill onto his streets. The last thing they all want is to be exposed and these idiots were running down the city streets, chasing people for fun. Izaya certainly won't report being attacked by werewolves though, the first two victims were already considered laughing stocks online last Shizuo overheard.
"Goddammit," Shizuo curses softly to himself. "I've still got some spare clothes here, right?" Celty nods, her helmet still on as she stays preoccupied with assisting Shinra. "I'm borrowing your shower, then. Fuckin' flea stink all over me."
As the blond exits, Shinra plops onto his stool and wheels around the table to cut Izaya's sleeve next. He groans in his sleep as Shinra gingerly touches his wrist, mindlessly tugging the adjustable bright examination light closer to the brunet's arm.
"Ah. Celty, my love, would you mind keeping Izaya still?" The dullahan immediately nods, shadows spilling from her sleeve and securing themselves around Izaya's arm and fingers like straps.
"Some of his carpals have a few non-displaced breaks and scrapes by the punctures, but his radius and ulna are snapped clean." Pushing up his glasses with his middle finger, Shinra theorizes that the Were tilted its head once it had enough pressure on the informant, likely to disable Izaya from fighting back. His attacker had missed his arteries by a few mere centimeters, giving Shinra the impression that it knew what it was doing.
With how sweaty the brunet is, he must have been running for his life for minimum of an hour straight. Izaya's extraordinary endurance is already commendable when his pursuer is just a two-legged Shizuo, but six quadrupeds on his tail definitely pushed his limits. They were assuredly playing with him, his wounds almost like that suffered by a toy in the middle of a game of tug-of-war.
Shinra stills as Celty approaches his side with a vial of analgesic and a still-packaged syringe. Bouncing slightly on the stool to stop his gloved hands from clasping together, he coos, "You're so caring and considerate, Celty! Are you sure that you don't wanna try on that nurse costume tha- Ack!"
Celty's hand slaps up the back of his head, phone jutting towards his face. "[Now's not the time!]"
Turning the water off, Shizuo shakes in place before reaching for the towel he set out beforehand. He's still pissy, annoyed that another set of clothes from Kasuka were ruined to save the flea of all people. His vest and pants can be dry-cleaned to get the blood and dirt out, but his shirt was tattered beyond repair and without it, the remaining articles are just spares. The pile of clothes still stink of garbage, blood, and Izaya, haunting one side of the bathroom with their stench as the scents of soap and shampoo radiate from the shower.
It's gotta be rearing around three or four AM now and he has work tomorrow. Hair almost fully dried, Shizuo briefly considers stuffing his apartment keys into the bag of spare clothes and transforming back to run home to save a few more minutes of sleep before work, but the risk of someone seeing him is too great. Be it while transforming back or just his naked ass unlocking the door like a lover kicked out of bed. It's entirely not worth it and Tom will always understand if he explains and apologizes.
Quickly dressing and exiting the bathroom, Shizuo spares a glance at the closed backroom door before letting himself out.
