Hmm I think she would just be brutal and pierce his head with it. I doubt there is another function for some that looks like a spear. But it is interesting to see that both of those guys already got ill. I think it has to do with the fact that alot of Psi has been released around them. I mean they got shot at with Psi Bursts, telepathy was used on them, Ageha did his unknown Psi thiny and Asaga his his dragon tail. I think all of that combined speeded up the progress.

....Now that actually sounds plausible O_o;
