Sketches of Cas
I love the ‘true form’ idea. (Thanks GO fandom, you’re making me pollute other fandoms.) I think that angels have 2 other forms separate from their vessels that are similar. ANYWAYS. Headcanon: Cas’s humanoid form just looks like the Olympic-trained version of Jimmy. He is a soldier so he’s super fit which means he’s thinner than tax-accountant Jimmy. And also a bit shorter.
And ‘GO fandom-true form ’ is the thing in the corner with the mask-looking thing.
