Basically one day at her job keylee was taking a blood sample from Rosey just to make sure she was healthy thankfully she was anyway so she took the blood sample over to the other ones to say for later just to compare but she accidentally tripped spilling the blood into some of Mike's blood she quickly recollected the blood but some of Mike's DNA went into the blood and over time started taking shape eventually FB wsb and keylee saw interest in it and decided to take it eventually it slowly formed to make roser Also fun fact she only looks like miker because she's Young when she grows up she will look more like Mike just letting you know
