Oh goodness, I thought it was fairly obvious that was being facetious? lol Though if we really buy into the "Meghan wasn't invited" theory then Pippa/the Middletons certainly don't come off looking good, especially if they were to show up at a wedding with Meghan as bride.
Eh. I doubt they are all that friendly. Certainly, if that were the case, one would think his girlfriend would be at the wedding as well, just like we saw with the others. (And no, I don't buy into the upstaging theory since Harry and Meghan were just recently at another one of Harry's *actual* friend's weddings.)
Why would his not include a Plus One when it's obvious now, that others had a Plus One? And how many folks are traveling to other countries, only to wait around for their significant other to come back from a wedding that they weren't invited to? I'm sorry but that's just weird, IMO. Not at all comparable to normal circumstances.
