I see what looks like Enchi but the coloring factor in it is really poor and the side clean-up factor not the best. The eyes striping seems pretty spot on for Enchi, and there is some definite side-pattern effects that may be that, but coloration wise it looks very wild-type. The coloration in Dad does seem different from a standard Banana and more Enchi-like than YB like to me. Off the top of my head, other morphs that do similar to what Enchi does to the eye-stripe is Spider (definitely not what we are seeing here) and Cryptic/Clown/Crypton complex (unlikely het Cryptic but still possible). Het Cryptic do tend to show some eye-stripe markers from what I've seen, while het Clown tend not to. Since it's the Dad it's coming from, I'd honestly throw him to a Clown or het Clown female if you have one to spare just to rule that out, and on the rare chance it's that, you have a pretty valuable morph proved out.
Best of luck figuring it out. I love the puzzles of it all.
