In an instant all of Kobra's anger is gone. He wants to hurt Sharon, yeah, but not Bruce. He likes Bruce and they're almost sorta friends... or they were.

"Bruce, I..." He goes from zero to guilty in .5 seconds, but as Bruce transforms into the Hulk, he doesn't even get his apology out before he starts to run.

Fuck, he's such a shit. He's no better than Sharon now. As he runs, his hand brushes a trash bin and the contents burst into flames. Fuck, fuck, fuck! He doesn't even look back at it as he puts everything he has into running away. He's been running all his life. He can do this.
