Thank you for playing and for the kind words!
Lakó isn't a recruitable crewmate, although I've had tons of requests for him, the hyena husband on Taun, and a few others to be added as options. If I happen to do a crewmate overhaul, they'll be first on my list.
Crewmates can indeed interact with one another, although it varies from crewmate to crewmate. Currently, Miles and Kuno have the most interactions, although I'm intent on adding more in future builds.
Thanks again :)
