Why would she risk her life in a battle?
Does she know and understand exactly why her brother died?
Does she know who Mandark worked for and what happened there that day?
Who would she seek for revenge, if she were to seek at all?
We would need much more insight to try and make such assumptions.
Hence the word "If"
We do not know why the PPG or DarkStar Council need her help but to risk her life in battle is maybe one of the reason to find the answer for the brother's death.
This is hard to say as we only see the destruction of the lab and maybe she could have gotten some info from the security camera or something. But like I say, hard to say
Disappear all this years and no answer and questions? I doubt she would just keep quiet and do not know anything
Who said she seek revenge?
