That's exactly what she had been doing. Fighting it, thinking this couldn't be happening, drowning in her emotional onslaught and the pain of fighting the transformation.

Somehow, Bruce's voice cuts through all the noise in her head and she manages one terrified look with glowing green eyes back at him...and does what he says, letting it happen. She's terrified of hurting him but she had to trust him.

An instant later, Betty is gone as the green monster stumbles to it's feet, holding it's head...staring at it's hands disoriented....and immediately attacking the first thing to spark, the remains of the exploded machine from before. Screaming defiance at it as it tears chunks of metal off, smashing it to pieces. The machine hurt Bruce, SHE MUST SMASH IT!!
