Good God, is this all about emulating what his parents did as a couple? Is he going to call her "Grace" under his breath and she'll have to answer to that name? Is he going to finance a remake of "The Country Girl" and it'll have to star Charlene...and of course, SHE will have to win an Academy Award for it too?
I don't like Charlene nor do I trust her motives, but even she doesn't deserve to have to totally emulate this dude's deceased mother in her actions and appearance.
I'm not concerned about that at this stage. It's an important anniversary for an event that turned out to be an effective fundraiser for a worthy cause and it's appropriate for Albert & Charlene to turn up. Let's see how the first six months or a year of engagements actually shapes up before we fret about a pattern that might not appear. And if the pattern you suspect does indeed become apparent, we can dish about it then.
