Allan is surely a master transporter to achieve such a fluid and easy transport.
It was clear earlier from the deference he received Rym was an important pactrid. Now we know he is a or possibly The Scoutmaster.
One thing I find curious is the pactrid strategy. They are not practicing an all out war on the humans despite the fact they continue to advance into their lands. It's a strange situation.
So they have encountered the Popper Prime. The idea of a time loop is discarded. Without the Prime, the Poppers would no longer be a threat. Is it possible to permanently de-skwish a being?
I felt his injuries would heal faster. They may have to do some moves to protect the family secret. Perhaps a visit from Ageny X to shield a secret government project. At some point those titanium pieces need to come out so it doesn't limit his shifting abilities.
The rebels have a strong network and must have been in place a long time. It must drive the powers that be crazy.
I don't believe Callum will be comfortable actively supporting the pactrid war effort in one of those refugee villages. His future seems tied to Rym.
