Gallador is much easier to get in, though the 'does one of Rand/Gallador make the other pointless?' worry remains.
(It is a general maxim in role-plays is that a group can handle any number of fighters, but duplicates in other areas tend to overlap their role)
At first the plan was that Rand represented choice number 3. If you remember, the eventual decision you guys made to become a group of equals removed that option, so now it is a choice of two.
I am seriously hoping I was right in that trailer and that the default positions would be for Rand and Gallador to go the other way to Galder. I very much think it will be.
So then I have to distinguish Rand and Gallador. Of course, Rand's megalomania means that, basically, he'll never be happy so he's ALWAYS going to want to restore choice 3 at some time. Gallador's ready to settle (though only to better himself in the long term).
That being the case, Gallador should have the best relationship with Adelmo. So his plots can probably spin out of that.
