No but can you just imagine Mrs Weasley getting to the magical afterlife one day and the first thing she sees is a girl with red hair sprinting towards her.
For a fleeting moment she thinks it’s Ginny, but as the girl comes closer she recognises the kind smile and the emerald eyes that are shining with tears. It’s Lily Potter.
Lily pulls Mrs Weasley into a tight hug and can only whisper three words before dissolving into tears.
"Thank you, Molly."
Ignoring Cas’s blunt and completely hilarious sense of dry humor for a moment, think about what he’s actually saying here. Castiel is the name given to him by God. Castiel translates roughly to ‘my cover is God’ or ‘shield of God’ in Biblical theophory—the ‘el’ suffix means ‘God’, and ‘iel’ means ‘of God.’ Cas is the name given to him by Dean. Deliberately or not, Dean removed the part of Cas’s name that means ‘of God’, and left him with ‘shield’. Castiel isn’t actually a Biblical angel—it’s a variant of the name ‘Cassiel’, who was an archangel in the Kabbalah responsible for observing the Earth with no interference. Making it up as we go, indeed.
