"We help you stay alive," Derek answered. "The government wants you dead. There is another version of you here, making it very easy for someone to find you. You don't know anything about this dimension, what historical changes there are, what money to use, what conventions exits. You can't go back without us. You have no idea what effect the rift has had on your body."
He leaned forward, adjusting the strap of his rifle. "We found you in few hours. Now granted, finding people that cross over is our number one priority, but the government is pretty eager to find you as well. How long do you think you'll survive without us?" Not that he had any intention of letting them go.
Alexis sighed. "Derek, don't scare them."
"They should be scared. People have died. People keep dying," Derek said with a shrug.
