Unaware that she was being watched, Masque froze at the familiar metal figure landing in the husk that had been the top few floors of the building across the way. A quick escape was the plan but, with his arrival the plan was changed. She couldn't resist, she never could. Whitney watched him through the scope of her grenade launcher and then rose, prepared to abandon it there. It was a one trick pony, she'd only brought one grenade, and anyway it wasn't even hers. She'd borrowed it during a raid on a HYDRA storehouse so if the authorities wanted to pin this wanton destruction on someone HYDRA could take the fall (Masque was rather sure they could afford another black mark). Not that the Nefaria couldn't use more notoriety with the feds, but that wasn't her particular aim tonight. The blame wasn't important so long as Hammerhead got the message. He'd know who it was from.
Hammerhead was no longer a concern, anyway, not with Iron Man on the scene. There was still time to leave, disappear into the night with all her mayhem behind her but why waste this opportunity? They were bound to run into each other eventually, she reasoned, why not sooner rather than later. Madam Masque pulled out her magnum, aimed and then fired a shot that she knew was pointless. His armor would deflect it if he didn't detect it and move out of the way first, but it wasn't meant to cause damage, only to get his attention. The damage would come later.
