Zingers don't have to be floating lines. They don't have to be entire stanzas. Sometimes it's all about the light juxtaposition. This stanza is one of the hearts of the poem. Yes, you could technically cut what follows it because it's variations on it, but I feel they add different hues. But this is the heart beating at least one of the main emotions of the poem.

Glad you liked it. I hope to keep the poetry coming, even if not this emotion, hopefully.
