When the palace is opened for safety, Peggy knows this is a situation that cannot easily be stopped. It's a defensive strategy, a barricade, a hold out. She continues going out and helping people, kedan or foreigner makes no difference to her, and she'll gladly take them to the palace if they so desire.

She spends some time in the palace herself, if only to do a little recon - the people who showed up can tell her just as much as the people who didn't. The security's tight enough to prevent anyone from going too deeply into the palace itself, but it can't hurt to observe, strike up conversation.
