Tyler is not a Meade. Tyler talks about getting his shares of the Meade fortune. As was stated when Wilhelmina was trying to have Bradford's child he left the Meade Publications empire to his children not his ex wife Claire. As such Tyler is not entitled to any of Meade Publications. As he was given up for adoption his claim to anything of Claire's and Hartley's is also suspect. Not to mention the fact that since both Claire Meade and Cal Hartley are still very much alive none of their children are entitled to anything they own. You cannot take property from your parents unless they give it to you of their own free will. There is nothing to gain a share of and while Tyler may not be educated enough to know this Wilhelmina would know this and would not see Tyler as a pawn.
