Tez was working in her lab at the PHOENIX base of operations (literally just a storage facility they bought and turned into a 'base'), she heard a noise outside.

"...Goddamn Combusted freaks-"

She immediately ran outside...and saw you, having woken up from being knocked out.

"Oi! Who the hell do you think you are?"

Tez held her robotic arm up to you...it transformed, activating a small buzzsaw, pointed directly at your face.
