This is a eulogy disguised as a love letter, written by someone who cannot admit the person they are describing is dead. The narrator keeps insisting they will see Dorian again while describing him entirely in past tense, building a portrait so mythologized it sounds less like memory and more like canonization.
Crystal child, double-Gemini / A million songs in his head
The astrology reference is not throwaway detail. It is the first signal this person has been turned into folklore. Nobody describes a living friend as a crystal child.
Nothing like being by his side / Wish I could see him again
The tense shift gives it away. 'Nothing like being' treats proximity as a finished experience, not a paused one. The wish confirms what the narrator will not say directly.
And since he left you can see it on everybody's face / Nothing is as fun
This is the closest the song gets to naming the loss. 'Since he left' could mean anything, but 'nothing is as fun' in present tense means the absence is permanent. The fun left with him and has not come back.
I just call your name / Life just ain't the same / I can't wait to hang with you again
Calling his name into the void is not hope. It is ritual. The future tense in the last line reads like self-soothing, the kind of thing you say when you know it is not true but need to hear it anyway.
The song ends still pretending reunion is possible, which makes it sadder than if it just admitted what it knows. Lenderman builds the whole thing around not saying the word 'dead,' but every line is soaked in it.
