The dna bit was that since Betsy no longer had a physical body she would have had to recreate her own dna out of thin air with no hair or blood or anything to go on, so then she made herself a new body, from a villain that was not a regular guest star and not often used...so then while she may look like Betsy is it really her down to her dna and if so how then did she accomplish that...and not everyone praised the change Iz...as for Kwannon she seems to be back but that's an entirely different story that makes no sense given that Kwannon was dead and gone years ago...
