Topher stared at the computer screen, monitoring Echo's vitals as she went on another mission. He chuckled softly, shaking his head in wonder.

"I fail to see what's so amusing."

Topher jumped at the sound of DeWitt's voice. He turned to her. "Ya know, you really need to stop doing that."

DeWitt rolled her eyes, walking over to the computer. "Extraordinary."

"It's been three weeks and Echo's vitals have been completely stable. She hasn't malfunctioned, she hasn't tried to take anybody out, she hasn't gone off mission. It's…incredible." He smirked. "Oh, I'm good."

"That's only her mission vitals; what about inside the Dollhouse?"

"No outbursts, no upending tables; we haven't had to call security on her for weeks."

"What do you think caused the change?"

Topher rubbed his hand across his mouth in thought. "I think it's Delta."

"Delta? That blonde active that came to us three weeks ago? Really?"

"Yeah. It completely defies the laws of neuroscience. For some reason, and I don't know how, Delta seems to have a calming effect on Echo. It's like…it's like Delta's her other half."

One hour later…

Echo stood at the bottom of the stairs, waiting for Delta to finish her treatment. She had a big day planned for them; swimming, yoga, painting, lunch and then more reading books. Echo loved the way Delta rested her head on her shoulder while she read to her; it made her happy.

"Hello Echo."

Echo looked up at her friend, smiling softly. "Hello Delta. Would you like to go swimming?"

"Yes, I'd like that." Delta reached for Echo's hand, smiling at the familiar warmth as Echo took it, gently leading her to the pool.

Up above, in the treatment room, DeWitt turned to Topher. "Well done Topher."

Topher smiled. "Thanks Ms. DeWitt. It really was nothing."

DeWitt smirked. "I'm sure it was. Back to work then; we have several actives going out on engagements today. It should be relatively busy."

"Yes ma'm." Topher smiled, turning back to his computer, his eyes falling on a profile that popped up on the screen. "Welcome to the Dollhouse Delta."
