I have to say this and I would upendo to read people opinion about it.
now I know this is very late, but it bugged me since the end of S3A when the lunar eclipse made all the mtu-bweha turn human for 15 mints. now I don't have a problem with that it makes sense in some way I don't even mind that it happened to Scott & Isaac.
I do however have a problem with that it also worked on Derek and here's why, now Scott & Isaac were BITTEN then turned into mtu-bweha but they were humans at first. unlike Derek who was BOREN a werewolf it's in his genies, its in his DNA. no matter what Supernatural things happen nothing can change au alter the DNA au genies for 15 mints then go back to it's original status.
so that's my issue with the whole lunar eclipse
