Bella was in a warehouse, but no one knew. She was tied up, and it hurt like hell.
Barry on the other hand was freaking out. Ever since Bellas father died Barry had tried to be like a father to her, so to him, it felt like his daughter, a member of his family was taken from him. And that wasn't something he was ok with.
Joe had recommended to Barry that he step away and let Jesse, and Wally find Bella, but like that would stop him.

"What the hell does this guy want?" Barry asks snapping at the group also sounding clearly annoyed.

"Wallace Trent, we call him the D.F.G" hank starts to say before Kara interrupts him.

"The Decomposing freezing Ghost" she says. "The offspring of two Metas.  Allison June, his mother had  the freezing and ghost powers, the unknown father can be assumed to have the decomposing powers"

"Untouchable" Barry mumbles to himself. "That's it, remember the guy; guys the man that slowly decomposed everything he touched. He's the biological father." Barry says. 

"If that's the case we're screwed." Joe says unoptimistic.

"Well we do know how to stop the decomposing part of him" Iris says.

"Phasing" Wally says, with a smile crossing his face.

"Exactly" Barry responds "Why did he target Bella anyway"
"To get revenge on me for killing his mother Kara says.
"Kara, it's really, you have to think about it.  Maggie, Hank, Lena, me even we are all hard to get to. You and  Barry are close friends. Bella was an easy target,who hasn't had training to spot suspicious activity like we have." Alex says a look of disgust on her face. She thinks to herself how could somebody  do this to someone who's just a kid.

"I'm so sorry Barry" Kara says. 

"It's my fault" Barry responds.

"We are gonna find her" Alex says.

"There's been reports of sightings of the D.F.G in Central Park he brought her there" a DEO agent says turning around in his spinning chair.
