Neptune square Lilith (orb 1.2°) creates concrete friction between the two planets. The orb is very tight; this describes a stable character pattern more than a passing reaction.
Here, Neptune in Leo in House 12 brings imagination, image, popularity, collective moods, and inspiration into House 12 (retreat, contemplation, long time, and possible confinement), with Leo style (presence, pride, creation, and the wish to be seen); Lilith in Scorpio in House 4 brings pure ideal, absolute demand, fascination, and refusal of compromise into House 4 (roots, privacy, and inner foundation), with Scorpio style (intensity, desire, crisis, secrecy, and invisible power).
Concrete friction: this aspect puts Neptune (imagination, image, popularity, collective moods, and inspiration) and Lilith (pure ideal, absolute demand, fascination, and refusal of compromise) into repeated friction: one can interrupt, inhibit, or provoke the other in concrete situations. Visible angle: Lilith near the IC (orb 5.5°) touches an angle; this aspect is easier to notice through private base, family roots, and intimate psychological climate. House 12 (retreat, contemplation, long time, and possible confinement) is in friction with House 4 (roots, privacy, and inner foundation); this can create blockage, inhibition, overreaction, or repeated conflict between the two fields.
