It was really bad writing, IMO. I'm so mad they reduced her to a plot device, then fridged her. If they didn't know what to do with her character, they should've just wrote her out instead of having Fade find her, then she could've always come back later.
Or, if they did want to have Andy hit her with a kinetic blast, then couldn't she have just, like, been badly hurt or something? The whole trajectory path was so dumb, too. From the way he struck her, she should've just awkwardly skidded across the floor and ended up at everyone's feet lol.
Ugh, I don't know. I'll probably just be salty about it forever.
