Lunar was the one who found Solar and pretty quickly proclaimed him friend. Eclipse who found them next, did not have that reaction dcfvghb. Flared up and got very protective and defensive over Solar being there until seeing how sickly he was, which got him to chill out. Solar being there was surprising, but it was easily agreed for him to stay there while he recovered. No one wanted to kick out this sad looking mer who was roughed up and underweight and just trying to find Someplace to be safe.
