Saw people talking about the names in the comments, my stupid ass though everyone already knew about it. So sorry in advance for my soon to be very neardy comment. It's just so interesting how much thoughts author put into everything.
Skylar has sky in it and Cirrus is cloud, clouds only exist if there's sky (kinda) and the name Lost in the cloud now explain itself.
But what's interesting is the type of cloud Cirrus is.
Clouds of that name are detached, hair-like and found at high altitudes. They are delicate and wispy, with a silky sheen to themselves. In the daytime, they are whiter than any other cloud in the sky. While the Sun is setting or rising, they take on the colors of the sunset being very beautiful color of orange, pink, purple etc. They are totally made of ice crystals and indicate change of the weather, they are related to thunderstorms and rain, also causing warming of the Earth. Some optical phenomenons are related to them.
Thing we were able to see is how Cirrus's eyes are changing colors. When he's sad, angry or lost they are fully darkish green. Meanwhile they turn reddish when he's onto something or when he's, I'll dare to say, looking at Skylar with lust, pretty raw and somehow scary feeling at the same time. Plus with Cirrys it's never calm, whenever he's around we have some turbulence, same as when Cirrus clouds are in the sky predicting rain.
