Tristan looked at the woman coldly. He was actually surprised that she recognized him after all this time, even in the mask that covered half his face and with the smoke making the other half almost indistinguishable.
He had a lot to say to his mother, but it really wasn't the time.
"Keep walking! Don't you see the house is burning?"
He tugged on his parents' arms, pulling them towards the exit. Weak and half-blind from the smoke, they followed him on wobbling hands for four steps before halting.
"What is it? I told you to hurry!"
Tristan was about to turn around, when through the roaring of fire and the firetruck sirens above, he heard rustling of clothing followed by a sharp metallic click.
The sounds could've had a multitude of possible sources. Clothing rustles all the time, and the click could've come from a belt buckle or a zipper.
