A/N: Only one more chapter to go and I'm thinking more of an epilogue. Thanks for reading.

Chapter 19

"I'd say your transformation is complete," Harrison Wells told Mon-El after the former Daxamite arrived back at the DEO. Doctor Milo had pulled him aside while Kara spoke with J'onn on how to handle their new prisoner.

"And it won't go backwards?" Mon-El asked.

"I examined some of the blood from Mr. Hill and his cells were being protected by the build-up of the sun's radiation. It would seem that the years he spent here provided him a barrier against the lead in the atmosphere. Though why he doesn't have the same powers as Kara does still eludes me. Anyway once his skin was damaged in the blast, the lead got in and has started to wreak havoc. He's in the containment unit as we speak," Milo spoke up.

"Ok but that helps me how?" The former Daxamite wanted to know.

"A DNA change is permanent. There isn't any going backwards. Milo mentioned Mr. Hill because basically between the DNA change and the yellow sun, there is no way you'll be worrying about lead, except when you develop x-ray vision," Wells explained. Mon-El heaved a sigh of relief.

"You guys have no idea how good it is to hear that," he said.

"We can guess. Now I really need to be getting back to Earth One," Wells told them.

"I'll find Kara. Thanks again for everything," Mon-El smiled.

"Just promise me we didn't make a mistake. I haven't known Kara that long but I know back on Earth One, there are people who care for her so besides her cousin you'll have them to deal with," Wells gave him a look.

"If J'onn or Alex doesn't get to him first," Milo chuckled.

"I would never hurt her. Besides don't you think Kara would kill me first?" Mon-El asked.

"Oh she would but there'd also be a line around the block to join in," Milo said.

"Good to know I have a vote of confidence from you guys," the younger man swallowed.

"Hey, the only vote you need is hers. She's been through a lot and she obviously cares for you. I know she wouldn't like us sticking up for her but we all see her as part of the family and family looks out for their own," Milo told him. Before Mon-El opened his mouth again, Kara walked into the room.

"Everything ok?" She asked noting the nervous look on her boyfriend's face.

"Yeah. I was just about to find you. Harrison would like to go back to Earth One," he said.

"I kind of figured. We're shipping Ben Hill off to the Phantom Zone. He can't stay here given his condition and he isn't going to tell us if we got all of the Kryptonite or not," Kara shook her head.

"Well until we are sure that we have it all, we'll just have to be careful," Milo smiled at them before turning to Harrison and shaking his hand. Kara then used Cisco's contraption to transport Doctor Wells back to Star Labs. Once that was done, she thanked Doctor Milo and told him to give his wife a hug for her.

"So is everything under control?" Mon-El asked once they were out of the lab and standing back near the main computer screen.

"J'onn says to call it a night. Pretty sure we could all use the sleep," Winn smiled slightly.

"Pretty sure I'd need more than just one night to catch up on the sleep I've been missing," Kara said.

"Hey before you locked psycho in the containment unit, did you snag my stuff?" Mon-El wanted to know.

"Oh that I did. Everything is in this bag. Also, I texted Clark and gave him an update. He says to relax and that he'd call Kara tomorrow," Winn said.

"Sounds good. Ready to go home?" Kara asked.

"Home sounds great," Mon-El smiled.
