As it turns out, that Assumption of yours was indeed correct, as your Parents quickly accepted your Proposal of adding half a dozen new Statues to the Troops guarding your Brother. Though while you were pleased with their Answer, it still meant that you would now need to create these new Statues with limited time, given that the new Lands of House Lannister became more and more messy with each passing Day. For your House didn't have nearly enough Boots on the Ground to keep all the new Vassals in Line, which in turn meant that your Father had no Intention of actually waiting for your new Creations, given that they should be fast enough to catch up to him before he crossed the Border.
It wasn't normally a problem seeing as you could by now create hundreds of Statues in just a few moments, but the standard Quality wouldn't do for something as important as the Safety of your Brother even if said Quality meant that they were more or less indestructible once you were done with them. What you needed to focus on was what troubled you before, namely the needed Improvement to their Perception, for Guards no matter how strong simply weren't any good if they couldn't find any Threats before it was too late.
And while your Brothers and Sisters were a bit more Perceptive than they were before, that was sadly a very limited Change to their Minds that allowed them to properly evaluate new Information, and didn't actually improve the amount of Information they could gather, Eyes made from Stone could only see so much after all. So the Days slowly tickled by as you worked on them, while several dozen Smiths freed up by the leaving of your Father's Host created their blackened Armours leaving just enough Space for the Gambeson to preempt the clinking of Steel on Stone.
It was as always rather satisfying to see your Creations improve as you continued to work on them, but the time pressure made sure that you couldn't indulge yourself in truly perfecting anything, which was quite annoying. But while you didn't have as much fun as you usually did when you created something, you still managed to swiftly find a few ways to improve their Ability to gather Information so that you could more or less accompany your Brother on his little Adventure through the Reach.
Your Father wanted Jaime to grow into his future Role by smashing the Rebels, Bandits and minor Lords defying House Lannister, but you were sure that he wouldn't mind if you gave him some Advice from time to time, as long as he still learned something. And even if Jaime didn't listen or rather didn't read what you had to say, it couldn't hurt to make the effort for your little Brother, and should he do something that will put him in Danger you can always just drag him back to Camp with your Statues, easy as that, no need to really worry, so why do you still worry?
Well, if you're honest with yourself you already know why you continue to worry about your Brother, it's because he's too soft and small, yes, far too small, why couldn't your Father see that? Normally a Suit of Plate Armour can make anyone formidable as long as the Wearer isn't completely inept, but on your Brother it looked different. Jaime didn't look formidable in the slightest, and neither did he look so much as a Year older wearing his Armour, it just made him look absolutely adorable with his still oversized Shield and those wide green Eyes of his.
He truly couldn't be compared to what you were currently creating, especially considering the height of your Statues and the glowing Warhammer with two Eyes added to make the collecting of Information more effortless. Looking at them, the two Statues you and the Smiths had already finished equipping both stood three meters tall, and were holding their dimly glowing Magma Warhammer which was greater than a grown Man before them in absolute Silence. They were simply what you had judged to be necessary to make absolutely sure that your Brother would be safe, but looking once more at them with the blackened Armour and the deep red Gambeson beneath, you had to wonder how to properly judge your Brother.
Truth be told, you weren't too sure if you could still judge your Brother for looking small in comparison to those two, no, you guessed that everyone but your Father would look as small as Jaime when compared to them. But then you knew like everyone else that your Father wanted Jaime to one Day take his Place as Lord of the Rock, so if your Father would certainly still look formidable when standing between your Statues, shouldn't that be the Standard that you would have to set for Jaime as well?
Hmm, there was time you supposed, and these things really didn't count as one of your Strengths, so it's probably best if you simply asked your Parents for which Standards they preferred for Jaime, it was a difficult Question to even think about considering how massively different your Parents were. Though you supposed that your Mother would already be happy if he stayed as adorable as he was, so there was a good Chance that the both of them had completely different Standards to judge Jaime's Growth by, yeah, it might take quite a while before you will get the Answer you sought.
Perhaps focusing on your own work is the best course of Action you had at the moment, seeing as Jaime was still the Heir to the Rock and the new Lands of your House were everything but safe. Which would of course only get worse considering that the King was apparently unaware of the planned presence of your Brother, something that wouldn't remain that way for much longer. No one would even so much as dream about going after your Father in his own Camp, but a little boy of ten that would be regularly sent out to hunt Bandits and Rebels with his Men would clearly be another matter. Thinking about it, he really made for quite the juicy Target, so yeah, you should probably focus on getting your Statues done, you couldn't leave his Safety in the hands of regular Soldiers and Knights in such a Situation.
