Her last memory before Trench was chaos— It was just like this one, sans the humans. Androids suffering from a massive virus infection spread rapidly across their systems. 2B's files were beginning to corrupt. The virus was multiplying at a terrifying rate. She took as many of her infected comrades down, and did her absolute best to bring herself to the only location with the least amount of android population. Desolate. Quiet. Skittering with a few infected here and there, but mostly secure for anyone else clean.

She wanted to die. She asked for it. A2 was kind enough to give it.

There's very little 2B thinks she would change from what she knows. "Do your job," she barks, keeping the SecUnit protected on all fronts and her eyes on ones that may need them most, "I'll do mine, and we'll get it done."

Protect human life. That seems mutual.
