Murphy was avoiding Bellamy and felt no remorse toward it. The sickness had passed from his system which uncovered not only his own natural scent; but cleared up his sense of smell that led to Bellamy's foresty, metal, alpha smell. Days on the ground had been fucked up and seemed to always be getting worse, but this was a sick twist. If presenting as an omega, a male one no less, wasn't bad enough; the one scent that sent his mind and body to a high had to belong to Bellamy Fucking Blake.
The first few days back on the ground had left them blissfully unaware since their suppressants were still coursing through their systems. And Murphy hadn't been at camp long enough to have his finally wash out, he thinks begrudgingly. Coming back he had been half delirious and so sick that his body focused more on healing than bonding. With his body back on track he now has to deal with this, he could only assume Bellamy still didn't know, he figured the eldest Blake would confront him on it. Or maybe he did and still didn't want to deal with a broken omega that he himself condemned. The omega in him shrunk back and radiated devastation for being unwanted by their alpha. He shoved those sentiments away and focused on keeping a wide berth from Bellamy.
Why can't anything ever go how he plans? It was a good plan, take out the bastards that tried to hang him and say that they died by the sickness, easy. Then Jasper had to witness it and now everything has gone to shit. Of course Bellamy would take his place, there was never any doubt which made it so easy for him to end it. His last person to get revenge on and to never have to think about having an alpha again- easy. If it wasn't for nature playing its course.
The adrenaline and still sick smell in the air was enough to get Bellamy tied up, but the closeness was too much. Bellamy's nose twitched, raising it and taking in a deep breath, eyes widening in realization. Murphy didn't get a chance to tie the last one on his neck as he zipped over to the other side of the dropship. 'Fuck, this wasn't supposed to happen!' his brain fogged over a bit as he fought against it. Bellamy was still processing but the moment his mind wrapped around the concept he began struggling against his restraints. Low growls escaped his throat and his constant pulling would probably make the bindings give in, and Murphy wanted to be far away when that happens.
He left Bellamy at the dropship, tied up- not hanging and put as much distance between him and the Arcers. It was probably suicide to go back to the forests with grounders; but even that was better than having to deal with a just made aware alpha. His alpha, the supposed other half of him. He refused to dwell on it, he shook his head of the idea but it wouldn't let up. He stopped once he felt he was far enough to keep his scent at bay.
He felt a lump in his throat, he hates Bellamy, he hates being an omega, hates being drawn to him, but most of all he hates the betrayal of the eldest Blake much more than even the death by hanging. He drew his knees toward himself and laid his head on them; pondering over the first time he felt like he was worth something ever since his father died for his sake. He stopped that thought cold, no- he knew that Mcbege had had his back on the arc, but even he too was gone; killed by grounders. With a deep breath and clenching his fists he tries to calm his thoughts and will away his secreting pheromones.
He stood back up and commenced walking with no clear destination in mind but as long as it was away from camp. Make believing that it was a survival tactic, instead of an avoidance of the inevitable rejection and animosity from the man who was now meant to be important in his life; he moved forward.
