In what context does all that grabbing occur? Is it driven by Dylan's intense desire ("I can't wait, you're so luscious") or is it her being initiated into exhibitionism?
I'm trying to understand Dylan's maturity in these scenes. Is he just a horny boy not able to control himself or a cunning manipulator and seducer?
I'd like it to be the later. We'll have to wait and see.
You pose a good question, but it is really neither of the options you present.
The answer to your question is found in the first playable day. Dylan's supercilious sister Ellie is given preferential treatment in the car ride from the airport. Dylan is punished for calling Ellie a slut, while Ellie continues to call Dylan a pervert after the fight is supposed to be resolved without correction. She even suggests that Dylan should spend the trip in the trunk...and neither parent intercedes. This clearly shows how the Parker dynamic has been for a while, and not in Dylan's favor. The one masculine achievement Dylan has is his soccer prowess, and his father discounts it. The only one with a supportive soft spot for Dylan is his mother, Sophia.
Everyone has seen that Dylan was nonplussed when he was in the tub with Sophia prior to date-night. Liam was about to come in and Dylan made no effort to stop squeezing Sophia's breasts. He didn't even flinch. Sophia had to make emergency moves to prevent discovery. L&P has made it clear that Dylan would like nothing better than to prove his manhood to his father by way of Liam discovering that Sophia is now with Dylan.
I agree with you that Dylan is inexperienced and clumsy in the kitchen, he is also high-T horny and he is trying to be a manipulator. I also believe that the other clumsy manipulator (Neil) sees his own awkward moves in Dylan and has figured out what is going on. This could prove to be interesting in the future.
