Given the amount of time it took them to actually own up to the scale of the disaster with the power plant, and that it was obvious they'd known how bad it was, I'm apt to agree that they're not going to be keen on help until it's gotten well beyond what they can handle. Which means it'll be tough for the Fen to handle when they come down.
