Stay inside and deal with the threats.

The three SHIELD Agents/Heroes have two very different Mutant dangers to deal with!

"Quake- keep those orbs out of harm's way," Black Widow says, trying to focus on anything but being naked, "Mockingbird- Slip and Slide Maneuver."
"Got it," the other two say.

Quake uses her powers to send the shockwaves towards the seemingly-endless supply of 'Boom Booms' coming out of the titular Mutant's hands. It keeps from them hitting the ground and destroying the foundation, but she can only do this for so long.

The other two naked Agents enact the maneuver to deal with Jean Grey. Mockingbird grabs two pieces of wood from the ground debris and uses them as makeshift weapons to strike at the objects floating around the Mutant. Widow, meanwhile, waits for her moment.

In a moment or two, the Agent has broken enough debris- you can always replace that mirror- to make a path for Widow to make a running slide through and end up next to Jean. She goes behind her and puts her in a sleeper hold.

"You're just lucky I don't have my stingers right now, honey."

She manages to knock out the Mutant peacefully and the debris starts to fall.

"Quake- send that at the explosives to clear a path," Widow calls out, letting the girl pass out in her arms.

She nods and keeps one hand blasting at the Boom Booms and the other to send some more debris at them. The small blasts make the area more viable, which Mockingbird takes advantage of to serpentine her way behind Boom Boom. Just like Widow, it is a sleeper hold for this Mutant.

"Just pass out and this will all be over, dear."

The naked Mutant passes out in the Agent's arms and the objects stop appearing from her hands.

"These kids are powerful, but not that tough," Mockingbird says, patting the naked girl's head as it rests against her bosom.
"Lack of SHIELD Training," Widow adds, similarly patting Jean's head.

All of a sudden, the stairs are blasted out and a group of figures appear- The Brotherhood!

Like the others, their powers are flaring and waning. Even so, they may be too much for our naked and weapon-less Heroes!
