Stellar was humming in her home, reading a book about parenting. Apparently the same Robotnik wannabes who made her, made another cloned lifeform, but this time from her DNA, and the DNA of the time traveling Hedgehog Silver.

It's been years since Stellar found the child, but just like Shadow, she felt the overwhelming urge to take the child in, and raise them. Her maternal instincts kicked in and she took the lifeform home instantly.

Now after raising her child for several years, Stellar has a better appreciation for everything Shadow and Sonic did in putting up with her as they raised her from infancy. It really made her want to apologize to them for all the trouble she'd caused them.
