Ermahgerd. Hypercreative idea.
So, since Kairo and and Menel are pretty good friends, I can really imagine Kairo popping up once in a while and teach your children. Y'know, like this:
Kairo: *Steps off the small sailboat and walks towards the gate, then knocks* 'Ulloooooo~? Anybody home?
One of your children looks over the fence, then shouts: Daaaaaddy! Mooooommy! There's a weird guy at the gate!
Menel comes looking, then shouts out of joy: Kairo! Come in!
Kairo walks in, talks a bit with Menel and Eala, the comes dinner time. . .
Kairo: I hope my visit doesn't disturb you!
Menel or Eala: Oh no no no! Very appreciated! We're glad to see you like the place!
-Indeed! Anyways, *pats his full stomach* how 'bout I tell your children some stories, eh?
Children: Yaaaaay! Story time story time story time~!
-Now now, come, younglings...
Kairo tells stories and blahblahblah yaddayaddayadda about how he used to patrol the streets with Menel and the good old times.
I can really imagine Menelmacil inviting Kairo many days, the children considering me almost like part of the family. Calling me "Uncle Kairo" or something like that.

Maybe I'm a bit too creative.
