Cordelia had been standing a bit off to the side, on her cellphone. As soon as Nathan approached and began speaking, she said her goodbyes and hung up, turning to the brothers.
"Okay. I spoke to a friend of mine. He says the PTB should be okay with you both coming. However," her gaze slid to Nathan. "They only consider Peter the Champion. That means his opinion is likely going to weigh higher than ours." Her attention then went to said Champion, her expression a somber one.
"They aren't going to listen to pleas of mercy. They don't understand loss. Or family. Only the mission," she offered by way of advice. Slipping her phone into her pocket, she added, "Now, we need to get to the abandoned warehouses on the South side, near the docks. There's a portal there that should be stable enough to use."
Once more, she looked to Nathan. "And try not to worry too much. If they were able to save my life and let me keep my visions, I'm sure they can help Mantis, too."
