@dcraus123 Not really, they're all just friends/acquaintances. Cale has tension with Sparkle because she's more interested in him as a fellow actor who has experienced the psychologically damaging effects of acting and became lost in the persona they created (But for Cale, he already mostly healed from that), plus the fact the Masked Fools know it was Aha who brought Cale to HSR (so she's kinda crazy about him as an entertaining unknown variable in the story).
Cale also has tension with Kafka, but half of that is due to Kafka's seductive demeanor and half of it is from Stelle's delulu shipping mind because she sees them both as her parental figures.
