"Hey." John says, to calmly.
Greg tries again to smile, at the attempted warm greeting of his friend, he fails miserably.
An awkwardness fills the room, which Sherlock quickly picks up on, as John takes a seat on the sofa next to Greg. "Cup of tea, John?" He asks attempting to fill the silence.
"Please love." John replies as he takes Greg's now ice cold drink from him. "I think Greg could do with another one as well." He continues, smiling warmly at Sherlock as he reaches to take Greg's along with his own into the kitchen.
John really was going to let Greg speak first, he really truly was. But when he hadn't said a work by the time Sherlock had returned with their drinks and excused himself to the bedroom to work on a case of some sort; which both John and Greg knew was just an excuse to get out of an uncomfortable situation, Greg couldn't blame him he would do the same if he could. But as Greg still hadn't spoken John decided he should probably go first.
"So, I take it, you don't know who that James is then?" He asks trying to be casual while taking a sip of his tea. Whether it was the question it's self or the fact that John had spoken braking the silence, that made Greg still, it's hard to say. But he visibly stiffened, tightening his grip on the drink and looking for the first time since he'd arrived back home.
"No." He whispers, but it sounds a little like a sob, "Sorry.". Tears fill his eyes, and he quickly puts his drink down, realizing he'll probably drop it soon if he doesn't. Hugging himself weakly, he looks away from John, apologizing quietly.
"There's no need to apologise to me mate. But tell me what's this really about? It feels like more than just, you know.
"And that's the problem isn't it." Greg replies with an anger that seems to come out of nowhere. 'I shouldn't be thinking of who that guy is, and why Myc could talk to him and not me. I shouldn't be jealous now, should I? I should be with Mycroft, and instead, I'm here." At this point, Greg stands and begins to pace as his anger rising again. "I'm here, screaming at you, while he's crying with a guy he's never mentioned before. And I just" Greg sucks in air to quickly "I just… I… John! ….. I can't breathe" he practically screams silently grabbing his chest and looking at John tears streaming down his face. He suddenly runs from the room into the toilet, gaging forcefully. John follows quickly, careful not to touch the now visible shaking man.
"Greg, you're hyperventilating. Having a panic attack. You need to slow your breathing." He places a hand on Greg's back, who is leaning of the toilet
"DON'T. He screams pushing John back so forcefully, he almost falls, catching himself on the door frame.
"John, I'm sorry. I… I don't…." Greg mumbles, as he slides down the wall curling in on himself. He bangs his head a little too forcefully for John's liking on the wall behind him several times, as if trying to snap himself out of the panic flooding his body.
"Greg." John says, clearly and calmly. "I'm ok, I know you didn't mean it. I shouldn't have touched you, I'm sorry." As he speaks John lowers himself to Greg's level, and that's enough to stop him banging his, but he still isn't breathing properly.
"Greg, I need you to focus on me, can you do that
"Try." Greg gets out, in-between gasps.
"Good." John smiles. "I want you to take a deep breath in and hold it for 3 seconds, okay?"
Greg nods. Taking a deep breath managing to only hold it for a moment, he chokes out the breath he tried to hold
"Can't …. Do …. Anything…." He stammers out angrily between attempted breaths, slamming his fist to the floor.
"You can" John assures him. "You can do this, just try again, okay?"
Greg closes his eyes and tries again to breathe. Breathing is easy, right? Of course, it is! Its instinct! You're a grown man! GET A HOLD OF YOURSELF!
"Greg!", John shouts, attempting to snap Greg out of whatever thought process has made every muscle in his body tense so much so that his muscles bulge slightly, and John is sure he isn't breathing.
"You need to breathe, Greg you're going to pass out. What use are you to Mycroft if you pass out?" John tries hoping his love of Mycroft can anchor Greg back to earth. It doesn't work so well.
"He…. doesn't …. got … James." Greg slurs through his quickly bluing lips, before slumping to the side and going completely lax.
"Dammit Greg." John mumbles as he attempts to lie Greg down, checking if his still breathing. Though the returning colour to his lips, and the steadying rise and fall of his chest is proof of this, John still needs to be sure. "Sherlock get in here. I need you."
Moments late Sherlock appears at the door. "What happened", he says just standing at the doorway, seemingly frozen by the unconscious Greg.
"He was hyperventilating so much he passed out. He'll be fine, just needs to lie down. Help me get him into my room."
"And where, pray tell, are you going to sleep tonight John." Sherlock mumbles as he grabs Lestrade's legs, lifting his lower half simultaneously with John, and taking him to the nearest bedroom, Johns.
"I will sleep on the sofa, if you don't want my company." John replies with an exaggerated smirk.
Once the two men have got Greg comfortable in John's bedroom, which is pretty much the spare room now, but that's neither here nor there. John intent on speaking to Mycroft as soon as possible, hastily takes a light sedative from the medical bag in the kitchen, placing it on the kitchen table.
"I have to go out, Sherlock. If he wakes before I get back and he's struggling to sleep or starting to panic again, give him one of these, and make him a cupper. Can you manage that?"
Sherlock who had gone straight to sit back in his chair, didn't respond.
"Sherlock."
"Yes, John?"
"Did you hear what I said?"
"Yes, if Lestrade wakes, I'm to make him tea and present him with one of those sleeping pills if he seems agitated. I heard you."
"This is important, Sherlock please, look after him."
"I will do as you require of me John, of course."
"Thank you." John responds, placing a chased kiss on Sherlocks head, before he leaves to go and have much needed words with Mycroft.
