Some observations

1. Maybe Ink had the tunnel closed because he was repelled by the smell of the cologne Victor spread to mask their scent.

2. It's a good thing that Riley kept her secret to herself. She was in the Army, and "Don't Ask Don't Tell" wasn't repealed until 2011.

3. I always assumed that Scratch and the Mallers took the SWAT Van. Even on her own, Scratch should be able to do a lot of damage to one of the Colonist's convoys that big, heavy armored truck.
