Thinking about an au where wwx was de-aged to the age he was after a few months after jfm brought him to lotus pier. Tiny wwx takes one look at jc and says 'jiang-shushu?' and jc, jc has to sit down for a moment, mechanically offering wwx a bowl of food when he crawled into Jc's
lap because jc remembers how much food wwx ate back then (and how much he still ate). He regains his senses and tells wwx that he's not jfm, he's not mdm Yu dressed up as a jiang disciple, but he's jc, wwx's little Shidi.
Wwx protests because there is no way that this older, mdm Yu-looking disciple is his squishy Shidi (an nickname wwx came up with when they were you because jc's cheeks were so squishable and then promptly forgot as they grew older)
And so jc spends a while trying to convince wwx that he's actually jc. Eventually the junior quartet, lwj, and lxc (who's been courting jc) finds them and when lxc reaches out to try and make sure jc is unharmed as lwj tries to do the same for wwx, wwx climbs
His (now very tall) Shidi, perches on his back and hisses at them like a feral cat, wrapping his arms tightly around jc's neck and proclaiming that jc is /his/ squishy
