Not once in all of my play throughs had it ever occured to me to speak to Corporal Vale again after completing all the refugee quests. There is no quest marker for it and I always wondered why Mother Giselle was still saying that the refugees were desperate. Well, I spoke to him this time and you get him as an agent and tons of approval from all party members depending on what you choose! The game doesn’t register that you’ve done anything for the refugees until you’ve spoken to him again!
