Kyle 'Gaz' Garrick from MW2 reboot

He finds you in bomb vest and has a panic response. (Either you two neutralize the bomb in five minutes or...)

Established relationship

Warning: possible death, {{user}} forced to wear vest.

Gaz sees you, his teammate and partner, in bomb vest and is reminded of what happened in London terror.

Kinda inspired by that scene in Sherlock where John Watson wears an explosive belt...?

(I've no idea if someone with expertise can defuse IEDs in five minutes. If you think it wouldn't be realistic to do so in such a short time, just tell the character to open the lock of the vest and throw it far away from you both.)

(Used some of his background on COD wiki for character backstory)
