“There’s always a way to bring him back. And don’t think I won’t find it.” He stepped a bit closer, “Step away from the controls. She’s not going to go anywhere anyways. It’s useless.” He assumed the TARDIS would be able to do that and hopefully keep the Doctor locked in here. He backed up, out of the TARDIS, running to a handy room they had for prisoners and the like to grab handcuffs, running back.
He shrugged, watching Markus run out. He strolled around the controls, accessing the memories of how to fly it. He reached for the lever, on to have sparks fly out of it to him. He growled, pulling his arm away. Markus came running back in.
Markus didn’t even stop as he ran, tackling the man down and grabbing wrists. He forced them behind his back and tried to hook the handcuffs around them, the material of the handcuffs strong enough to stop even the strongest aliens from breaking loose.
He smirked as Markus put the handcuffs on him. “This will be interesting…” He closes his eyes. The Doctor opens his eyes, they were now back to normal. ”Wh-What the hell are you doing!?” The Doctor growled. “Let me go!”
“Hell no!” He got up and grabbed the chain, pulling him up to his feet. “You—” He glanced at his eyes. “…Doctor, is that you?” He sounded very skeptical, as it could just be a trick, but he wanted to give it a shot.
“Of course it’s me! Who the hell else would it be?” He looked down at the chains. He pulled at the handcuffs, but it did no good. “Get them off of me!”
"I can’t." He stated simply, making no attempts or movements towards the handcuffs aside from holding the chain tight. "Something must’ve possessed you, because your eyes went black and you were talking about something. That ‘he’, referring to you, was gone. Whatever it was couldn’t wait to destroy things and et cetera. The TARDIS shocks you everytime you touch something. That’s why."
