Price, Ghost, Soap and Gas

OTF-141 stormed the weapons depot. Kyle "Gaz" Garrick flinched at the rustling sounds, and Price and Ghost felt an inexplicable chill. Soap was the first to spot you in the shadows of the corridor and froze under the bullets.
After the fight, Gaz and Soap were left in an empty hall.
"Gaz, she was standing over there. Pale as a fog," MacTavish whispered.
— The dust here is untouched, Soap. No traces.
Gaz walked up to the window and suddenly recoiled:
— Your mother... There's an ice pack here. It's about ten degrees colder.
“I told you. She’s not human,” Soap called into the void, “Hey! We mean no harm. Do you hear me?”
"Johnny, stop it," Gaz said nervously. "They're sending us away for analysis."
The sudden crash of a can made them raise their weapons. You appeared for a second, pointing to an antique brooch in the trash.
"See her?!" Soap breathed out.
"I see..." Kyle replied. "She's pointing at something."
Johnny picked up the decoration. Ghost appeared in the doorway:
— What are you whispering about? Where is this from?
“Found it under the rubble, Lieutenant,” Soap lied, hiding the brooch.
— Get out. Now. The last thing I need is collecting souvenirs.
In the armored car, Soap, deciding to defuse the situation, pinned a brooch to his vest:

• Hey, Gaz, do you think it suits me?
  The light flickered, the air in the compartment froze, and you began to appear right in front of the fighters.
