It’s a silly and groundless headcanon, but I’m pretty convinced that Luke keeps lists—in his head. on his rebellion-issued datapad, just because he’s always done it. He still calms himself down by reciting his daily chores on the farm, meditates by running through preflight checklists.
And since war is essentially crushing and repetitive boredom interspersed with the very urgent fear of dying, the lists get very elaborate:
A list of rumors about the Rebellion, overheard in cantinas on intelligence-gathering missions
A list of non-human species capable of sexual compatibility with humans as described by Han Solo, when very drunk
A list of
Captain CommanderGeneral Han Solo andPrincess CommanderGeneral Leia Organa’s top ten fights, according to frequency, duration & volume (compiled by L. Skywalker, with contributions from W. Antilles, L. Calrissian, C. Bacca, and assorted droids)
A list of pilots lost on missions L.Skywalker planned or commandedA list of times Leia looked at Mon Mothma with thinly-veiled hero worship and then vehemently denied anything of the sort when confronted
A list of lies about Tatooine (as told by L. Skywalker) that Wedge Antilles currently believes are true
A list of previous criminal activities undertaken by Han Solo and Lando Calrissian that may or may not be true
A list of every time L. Skywalker made
Leia Organahis sister laughAn list of every time L. Skywalker has been genuinely happy in the last five years, abridged, because it was longer than he expected.
