Personnally, I never train Heather as she sucks.
So when I do this chapter, she's too weak and will be killed by anything.
And personally, even if Heather was at a good level, one senator is too far and I have to kill it ( :( ).
So for just 500 or 250 BEXP, I don't want to train Heather (and killing senators is sooooooo great *-* plus they are just bastards).
