The hunky Clint Barton aka Hawkeye/Ronin does some bare-chested cooking for his ex-wife Bobbi Morse aka Mocking Bird when suddenly Bobbi goes all crazy and tries to stab him! Talk about an ungrateful bitch! Doesn't she realize how lucky she is to have this stud cook for her? But wait, it seems that poor Bobbi isn't responsible for her actions.
Early on in her career, The Black Widow was injected with nanites which she unwittingly spread to her "friends, allies and lovers". These tiny particles can manipulate their hosts into a homicidal rage. The nanites' unknown controller has one goal, to kill all the people that hBlack Widow has ever loved, and the first target is her ex-boyfriend Clint! Hence Bobbi's sudden murderous outburst. So 'Tasha passed the nanites to Clint who the passed it on to Bobbi? Its like a homicidal venereal disease! Luckily, BW arrives and subdues Bobbi... with a (counter-nanite) kiss!
