User blog:FanMade Girl 20/Melissa Roxburgh's two characters on Legends and Arrow

Does anyone eles think that Betty is Blake's grandmother because of their uncanny resemblance to one other plus they would both be the right age to be grandmother and grandaughter plus the Legends have runned into other familes ansectors before but they only know of the Yamashiro family since they're a big deal in Arrowverse while the Seaver family aren't and lets assume Betty married into the Fuller's family an few years after they encountred the Legends which a two generations later lead to Blake played by the same actress. Smallville has done a simliar tactic with Kristin Kreuk's character and her female ansectors to show off their family ressemblance plus there are a few cases of a girl looking excatly like her grandmother instead of her mom instead. Anybody else want pitch in their  opinions  of this matter.
