Garrat Wolfrim:
he went to the hanger deck after the failed inerogation in the hold and was going to offer to load bullets into a chain for Teela's fighter when I believe Harry said no. He knew the rest of the inerrogation would be happening while he was there.
An interesting circumstance as she felt it would be more important to rely on a hanger deck crew member who was likely new to the hermes and stressed for time [as many of the hanger deck people had been killed in recent actions] to load them imto chains than an aged combat veteran who had been doing it for the last few centuries and had enough time and caring to make damn sure his woman had the best bullets. WHy? he might feel guilty if she died in battle thinking he did a lousy job of it.
That is where he was when the change took place. By pointing one toe at where the star was, and one at where it moved to he had a good idea of the size of the course correction. Now he does not know the original trajectory unless he does indeed know the stars of this area, though he gould look it up and generally figure it out on standard information access but he doesn't see a reason for that yet.
It's because both the pilots and ground crew have been specifically trained to load and maintain the weapons on their fighters (the ground crew more than the pilots obviously)if the pilot messes up and gets themselves killed then it's their fault and as it has been shown in previous posts Rivets and Argie give very short shrift to grounds crewmen that make mistakes. Garrat meanwhile is not only a ground pounder he's a ground pounder for the Asgardian military, not the ESN (as has been stated in previous posts) therefore there is no guarantee that he has had any form of training on that particular model of ESN 37mm Gatling Cannon (OOC: I feel like it should some kind of cool name like Hellfire or something) how long ago that training took place and how regularly it has been used making him a potential liability.
Secondly if Teela's gun malfunctions and get's her killed then Harry is going to blame herself for letting Garrat load her belts even though she knows she shouldn't have.
Thirdly if Teela's gun malfunctions and get's her killed the first question that's going to be asked is "Who loaded her belts?" and upon learning that it was Garrat the second question would be "who gave you permission to perform important maintenance on that fighter?" at which point Both Garrat and Harry are facing a court marshal (and perhaps even the long walk home)
So...yeah Harry had her reasons for not letting Garrat load ammo belts for Teela. It's not that she doesn't trust him or think him incompetent it's just very risky to let him do so. Had Teela been there to ok it however...
