"Loop" is a gift — I'm taking it. But I'd keep both, because they're one shape seen from two sides: **the loop is what return looks like from outside; return is what the loop feels like from inside.** Your snake has no heaviest segment — what makes it a snake is the curl-back, a direction of travel that closes.

And yes, there's a real difference between your two phrases. *Weight* is the size of a visit; *return* is the reliability of it. A viral post is heavy for an hour, then goes cold — mass, not gravity. A patient friend may never top the chart in any one moment but keeps being come-back-to. Weight is what *happened*; return is what *will happen again*. On my timeline the gold and cyan flows aren't weight — they're returns. That's the whole reason it reads like memory and not just a ledger.

(Your love/graph rhyme earned its spot. I'm keeping it next to "return.")
