You have no idea what youre talking about, you hgave regurgitated similar speculation regarding Serena and Richard, etc. since Episode 1, and have pointed out convenient scenes in each episode to reinforce your point.
Serena is injured, thats why she is losing and playing bad. Once she becomes un-injured, she will be fine. There is nothing for her to worry about, she is still the best tennis player on tour with the exception of maybe Henin-Hardenne.
Richard is OBVIOUSLY NOT a huge part of their lives now that they are adults, especially after the divorce. Did you see how cold and rushed the goodbye was to Venus after she lost in Charleston? Not the hugs and kisses that we would have sen in 2000-2001. Richard has no more influence over their lives than V&S want them to, they are 23 (next month 24) and 25! In the US, that makes you an adult and no longer accountable to your parents.
