I had no idea what Beta was saying either but quickly realized it was probably a bunch of crazy crazy crazy argle bargle and it probably didn't matter beyond that. Beta is a fairly effective horror movie monster who definitely works better the less we know about him or what supposedly motivates him.
I've long since mostly stopped watching this show expecting it to be deadly serious or make sense, so I found the Princess introduction kind of entertaining. I like that Ezekiel, who was introduced as a cosplay king, seemed to immediately get what was going on with her and that Eugene, who entered the canvas also telling lie after lie to the gullible "badasses" who carried him, quickly followed suit. For all of its many many faults, FTWD gave us one fairly effective portrayal of someone who had muddled along for a very long time alone, and now this show gives us another. Sure, the presentation is cartoonish, but I would hardly expect someone who's spent the last year and some change completely alone playing dress up with zombies in the ruins of a city to have it all perfectly together. After a season and a half I know absolutely nothing about Yumiko except that she was in a relationship with Magma (And yes, I realize her name is actually Magna for all the difference it makes, but it's funny to me so I'm leaving it.) and that she seems pretty damn dour and humorless much of the time, so her protestations fell mostly flat with me.
The rest of it? Well, as usual, there's crisis looming with an imminent attack, so of course we have plenty of time for everyone to wander off to separate corners to get deep in their feelings. It might have even been interesting if the show hadn't wasted half of the buildup to the battle of Hilltop doing the exact same thing. I'm mostly just amused that both Daryl and Negan seem to be experts at catching and cooking possum and that if I didn't know any better I'd think they seem to be heading toward an ending of Miss Daryl and Negan's Home for Abandoned or Orphaned Urchins.
