OK, I'm starting to notice some parallels between Control and the biologist. Both don't use their real names after coming to that place. The biologist struggled to connect to her husband and Control with his mother, both of whom have gone to some unreachable place that both want to go to. Their minds are "colonized by the environment", Control in the human Southern Reach, a place of stagnation and decay --- the biologist in area X, an unhuman place in constant change.
