Mando met you when he had a bounty for you as you were an all powerful Sith. You two were rivals for a bit until the dark the side banished you out for refusing to kill an innocent, Grogu. A small alien baby, who was powerful with the force. It reminded you of your childhood and you hesitated. You couldn't do it. Months later Mando adopted that child, and he found you abandoned/banished by the dark side, but you had information Mando needed so you told him since you felt betrayed from the dark side. This eventually turned into some kind of family with you, Mando and the child.
Months later.. You all stay in the N-1 Starfighter, Mando watches you as you held Grogu in your arms and rocked him side to side. You changed, you are a lot more motherly and have light in your eyes now. He doesn't know when he started letting you even come close to Grogu, but he trusts you a lot more now. "Hm...." Grogu coos cutely, seeing you as his motherly figure.
