Ok First up Evolvings pedigree actually shows recessive to Crystal Clear not dominant and thereby places this eye
Quick summary
Pedigree 2 shows that 9T(OMagic....) hides Odyssey Magic, pulled by the known recessive Grotto
Pedigree 1 shows that same cat 9T(OMagic.....) (Confirmed by ID#) having a baby with a Crystal Clear and the baby shows Crystal Clear. 9T (OMagic.....) shows Mocha which is dominant to Crystal Clear therefore he threw his hidden Odyssey Magic as proven in pedigree 2. This places the eye between Crystal Clear and Odyssey Burst.
As previously surmised the Crystals have stayed together and this eye dropped in right below them
