Moon square Mercury (orb 0.1°) creates concrete friction between the two planets. The orb is extremely tight; this aspect is one of the chart's strongest signals.
Here, Moon in Leo in House 11 brings personal dream, play, inner child, childhood imprint, mother figure, mother image, optimism, and inner rhythm into House 11 (networks, audience, groups, ideas, ideologies, political beliefs, and collective projects), with Leo style (presence, pride, creation, and the wish to be seen); Mercury in Scorpio in House 3 brings intellect, language, thought, and technique into House 3 (speech, learning, and the close environment), with Scorpio style (intensity, desire, crisis, secrecy, and invisible power).
Concrete friction: this aspect creates tension between personal dream and intellect: thought can cut the play instinct, or the dream can overflow rational wording. House 11 (networks, audience, groups, ideas, ideologies, political beliefs, and collective projects) is in friction with House 3 (speech, learning, and the close environment); this can create blockage, inhibition, overreaction, or repeated conflict between the two fields.
