Headcanon: Much Like Grey Wing Being Silverpelt And Clear Sky Being The Daytime Sky, Jackdaw's Cry And

Headcanon: Much like Grey Wing being Silverpelt and Clear Sky being the daytime sky, Jackdaw's Cry and Falling Feather are the Sun and the Moon respectively.

Falling Feather is the Moon. She is shown to have an affinity for water, drawn to its allure but never fully commiting to it like a Riverclan cat would, much like the Moon has influence on the oceans yet is not in full control. She is seen to be conflicted in many of her decisions, especially those regarding leaving Jackdaw's Cry as she is and keeps close to him, but stays firm in her choices; relating to the Moon, its light is that of the Sun's and it is always seen as half of the cycle of the two, but it has it's own changes (the moon phase cycle) and moves of it's own accord rather than anything related to the Sun. She is calm and level-headed, but stubborn in her choices and firm in her beliefs and wants. She fits the Moon due to the way she handles her choices and relationships.

Jackdaw's Cry is the Sun. He is shown to dislike water and prefers prey found usually during daylight, and is even part of a hunting patrol to catch a hawk out of the air and is even later commented to be able to jump the highest out of the traveling cats. This comes into play later when he's shown to easily jump high flamed during a forest fire. He is passionate and confident, constantly forming strong opinions on topics and speaking his mind, yet he also knows when too much is too much and can quickly calm down. He fits the Sun due to his bright and passionate personality and preferences.

Of course, there's probably better evidence for this, but I just skimmed the wiki after coming up with the idea.
