Have to put in the mimmoth traps to avoid immediate re-contamination? Do you need more?

I have no idea what the Chung twins did to their room. It may need to be sealed until we can ensure it is not a portal, or a window.

Where might they wish to go?

First we need to find Mr Uggla. The children are not registered time manipulators, but considering the statistics, we should rule that out first.

I have some glue traps in my ship's hold if you should need them, Frau Lowey (not recommended if you have pets or absent-minded maids though).
