It's a rare voiceline but sometimes if Bardin dies Kerillian says "Tell no one, but I will miss the dwarf" and I find that really cute (seeing how elgi are the dwarfs' ancient enemies).
ive noticed that, of all the heroes, kerillian is the only one belakor is attempting to turn to chaos. slaanesh is quite fond of elves after all, and khorne has seen his share of elven cults here and there. He also makes illusions to there being something about kerillian that no-one else knows about. Also, through these lines, kerillian seems to be more familiar with belakor then most. People say saltspyre is the most vulnerable to chaos corruption, but I think it would actually be kerillian. Keep in mind, in naggaroth there is an extremely large cult of slaanesh led by the witch king's mom; so chaos corruption isnt exactly something unknown to elves. Regardless, Im sure we will see more of her story soon at some point.
Summary: Shots 1-5: Clearly missed. Shots 6-9: Missed due to recoil (bad spray control). Shots 10-11: Very close, but recoil and inaccuracy make these reasonable misses. Shot 12: Likely didn't actually fire because Saltzpyre was already dead.
