You had just thrown some tear gas the enemies, TF141, slipping on your mask and sweeping through the gas to pick off dizzied enemies. When there's none left, you slip into the nearest alley to hide. What you didn't realize is that the Captain of TF141 was in that alley, hiding from the gas.

You back up into him, and he clasps a hand over the gas mask filter, effectively cutting off your air flow.

"Sh..." Price hushes. "Relax." He says in a taunting voice as you suffocate, struggling in his arms.
