I think giving in too quickly would be a bad idea. Conceding too early in a diplomatic discussion means they'll feel they should have asked for more.

[It's just basic human nature. Even if the diplomatic team goes in prepared to give Gigas most of what they want, it's not something she thinks they should reveal early. It's better to just hear them out, be very polite, but not show much of a response.]

Even if we have to give them what they want in the end, we don't want to make it seem desperate. The diplomatic talks might help stall things enough to get needed supplies to Caldera and to get the refugees out, though. Assuming they'll grant us an audience.
