"It's a pleasure to meet you, Dr. Banner-"
"Skip the formalities, Sam, you need to get off your feet. Into the car." Bruce interrupted, efficiently pushing the massive man into the private car Tony had forced upon him, telling the chauffeur to park at the lab entrance of Stark Tower. Having moved permanently into the newly renovated Stark Tower with Tony and Pepper, Bruce had been... cautious to interact with anyone not required in the tower, but Sam's case was different, to say the least. Late in the night, waking restlessly in his "Bruce-I-don't-care-what-you-say-you-can't-keep-sl eeping-in-the-lab" bedroom, Bruce had blearily reached out to answer his private phone which had been ringing through his dreams for much longer than the normal 7 rings.
"Hello?" He said into the phone sleepily.
All he got in response for a minute or so was ragged breathes, but just when he was about to hang up "Doctor," a shallow breath "Banner. I'm Sam, the guy who emailed you for contact about," breath "your specialization in cellular mutation, but," the incredibly shaky voice petered out, audibly embarrassed.
Dr. Banner was fully alert and out of bed by then, hastily sliding pants on while making a mental check list of symptoms in Sam. "But what?"
"I'm at the bus stop," breath "across from the tower and," a small hiss of pain "I'm... I can't walk over there. Could you... Could I get a ride?" And that's how a thoroughly embarrassed and apologetic Sam ended up having a one second car ride to Stark Tower where he was deposited in a wheelchair Bruce had preemptively packed in the car, and was wheeled into the newly redone laboratory that Tony was working in. Ignoring Sam's painfully false remarks of "I'm fine," and "This really isn't necessary,", Bruce reached to type in the lab password and pushed himself and the wheelchair-ie in.
"Tony, I'm gonna need one of the cots. Now." To his credit, Tony's eyes only widened fractionally as he took in a giant and sheepish man having been wheeled in his lab, and he pulled one of the cots away from the wall without complaint.
"Doctor Banner, I really am fine, just a bit sore. Err, tired." Sam protested, carefully lifting himself out of the wheelchair and and onto the sterile cot.
"Well excuse me if a man who all I know about is his entire cardiovascular system was mutated calls me at midnight saying he can't walk a few feet and I get a bit concerned." Bruce said, forcing his voice calm.
While Bruce was fussing about getting an oxygen mask for Sam, Tony pulled the good doctor to the side. "If I may ask, which I may-what the hell is going on?"
AN: I'll leave it here for now... I have two more chapters prepped, but if you guys want longer chapters than this ,I'll just combine them. Let it be known that this story was written before I saw Iron Man 3, and every single time I write it it seems to be a 2 in the morning. The whole trials-having-mutated-sammy thing is just my headcannon. This story will be the first installment in a series of SuperAvenger fics, all set in the same universe. Until next time, eat some cookies, rub some fluffy cat bellies, and make more fanifction! Bye!
