Spike lets go of Raphael's neck and taps at his shoulder. "Put me down," she whispers.

Raphael sets her down and glances around the top of the building.

"I could've technically used the grappling hook," she whispers, squinting at a crate.

"Figured this was faster," he whispers back.

She points at the crate and starts towards it.

She jumps on top of it, and swings her mace to block the swing of a sword.

"Karai?!"

"Sanchez?!"

Karai breaks the lock the weapons are in and swings her sword down to split Spike's skull. Spike kicks Karai in the abdomen and knocks her backward, before jumping off the crate and planting both boots into Karai's chest, pinning her to the ground. "Red, it's Karai." She kneels on the ground, pressing one knee into Karai's chest.

"I kinda guessed," Raphael remarks, striding over. "I was coming, since it seemed you were in peril and needed help," he continues in deadpan, glancing down at Karai.

Spike draws her dagger. "What are you doing here?" she growls.

"I don't believe you need to know," Karai answers.

Spike glowers and places the dagger at her neck. "I believe I do."

Karai chuckles. "You wouldn't."

"The first time I saw you, you were going to kill countless civilians and had a gun on me. Believe me, I would."

Raphael nudges Spike's shoulder. "Don't go all vigilante on us, okay?"

"You're throwing off my intimidation act," Spike hisses. "Pipe down."

Karai gives him an amused look. "Are you her commanding officer?"

"No, she never listens to me," Raphael states.

Spike swats at his knee. "No bantering with the villains." She glares at Karai. "Well?"

Karai smiles.

Spike glances at Raphael. "Get Leo."

~Trouble Strikes Again~

"Karai." Leonardo lands next to Spike and looks down at her. "Is the Foot with you?"

"No, just little old me."

"Why should we believe you?" Leonardo asks.

Karai shrugs. "You don't have to, I suppose." She sighs. "Look, call your dog off, and we can talk like mature people."

"I'm not a dog," Spike mutters.

"Wolf, then."

Leonardo nods. "Let her up, Spike."

Spike stands, knife still out.

Karai stands and raises her eyebrow at Spike. "A little paranoid, aren't you? What have I done to cause that?"

"You tried to kill me, and destroy all of New York," Spike explains sourly.

Karai shrugs. "Fair enough." She turns to Leonardo. "What are you doing here?"

"Investigating suspicious activity." Leonardo leans forward. "Your turn."

"The same as you, apparently," Karai says, sheathing her sword. "I thought it was you."

"We thought it was the Foot." Leonardo frowns.

"She could be lying," Raphael warns.

"It's not the Foot, unless they have plans I'm not in on. In which case this'd be very awkward."

Spike glares at her. "Why are you allies with the Kraang anyway? What do they want?"

Karai glares back. "Why do you think I should tell you?"

"Girls, please." Leonardo glances between them.

Karai sighs. "I don't know why we're allies with the Kraang. Sacks and Stockman do. I don't know what they want, but they give us mutagen."

Raphael exchanges glances with Leonardo.

"I wish we had a truth serum or something," Leonardo mutters.

That's right when the windows shatter in the building beneath them.
