I imagined that during Ken and Miyako's wedding, Wormmon was going to "give away" Ken, but he found that he could not physically or mentally let go of him and just kind of clung to his shoulder awkwardly for the entire ceremony while everyone just stared at him with exasperated smiles.
Legit, creepy overly clingy Wormmon
is
fucking
canon
And I imagine Wormmon third-wheeling hardcore in that marriage, it gets annoying at times but he's too adorable to get too angry at. Also, after Miyako's very short maternity leave (this is my canon, bye) ends, Wormmon is 101% happy and excited about babysitting all of Ken-chan's seeds/procreations/extensions of his self their kids, ahem; he ends up being extremely helpful in raising all their children.
