Causal medium

"The successful rescue from the Batris in Episode 20, where Geordi plays a pivotal role in navigating the away team through peril, directly enables Episode 21’s willingness to risk exploratory missions (i.e., sending Picard down) — because technical competence in evacuations and sensor interpretation has now been demonstrated."

Urgent Escape Through Collapsing Engineering
S1E20 · Heart of Glory

"Geordi's experience of transmitting complex visual data through his VISOR in the Batris wreckage foreshadows and parallels his confrontation with an equally incomprehensible threat — the cloaked Interrupter weapon — in Episode 21. Both involve perceiving and interpreting invisible or overwhelming sensory inputs under crisis."
