I am conflicted about this episode. I realize that all things that I would hand wave in TWD universe are hard for me to do with Daryl and Carol roaming around Europe. Three years in, I still find it preposterous that they are in Europe. Daryl finding his way to Barcelona without help. A leper community surviving all these years without medical treatment. How are all these people infected? The disease is not easily transmitted. Okay, I'm done.
I think they actually handled Daryl ending up in France really well. I always felt the most logical answer to the constant question of how he would get there was by boat. Having him get kidnapped and put on a boat to France was even better because - unless he found evidence Rick was in France - there was no reason for him to try to get there on his own. They're 12 years into the ZA so I do find it believable that some people are trying to re-establish traveling - we'd already seen that the CR has helicopters. Boats, ships, planes, etc... - it just makes sense to me. But they didn't handle Carol going to France as well. There was just no reason for her to leave the CW and having her say it was because it was "too quiet" was just weird. Daryl was out traveling around the CW districts for a year before leaving to go exploring and that didn't bother her at all. But now he's a week late and it's suddenly "too quiet". Just didn't make sense. Plus the plot convenience of them landing in just the right city and immediately finding Genet's group - too much coincidence.
I also don't have any issue with Daryl going to Barcelona on his own. Antonio gave him a map and I believe Daryl is capable of following a map. Even if the words are Spanish, all he needed was for Antonio to show him where they were - starting point and ending point. He can follow it from there. Plus, the promo for episode 6 shows he won't continue to make that journey alone - perhaps Paz had the same concerns you did. lol
As for the leper community, I don't find that surprising either. Leprosy is not highly contagious, but certain living conditions can make it more easily transmitted - i.e. poverty. People living in a post apocalyptic world - especially in the early years - would be living in similar conditions. Consider the conditions at the prison in S3 - it was dirty, no plumbing, food and medicine were scarce, etc... Poor hygiene, malnutrition, and lack of medicine/vaccines create conditions ripe for diseases we no longer consider serious to crop back up. We really should have seen more outbreaks of other diseases over the course of a decade.
I haven't been posting week to week, but I am really enjoying season 3 so far. The last 2 episodes in particular were really good. I loved the battle against Los Primitivos and Daryl showing the leper community how to fight for themselves was really cool. The fights on the train were great too - I love when they add a little bit of humor. Daryl and that guy taking a minute to catch their breath was so funny. Little Rosa was so adorable - I loved her counting down 4 bullets/4 demons. That was a side quest and doesn't really tie into the overall story, but I think it was needed for Daryl to overcome his emotional shut down and it was something he had to do on his own. It is typical for him to shut down emotionally for a while when he's grieving and he needed that reminder of who he is to move past it.
I can't believe there are only 2 episodes left this season. I'm really excited to see how it all pans out. The King and Fede need to pay for La Ofrenda - especially Fede trading Justina to protect himself. Roberto and Justina are such a cute couple - I'm rooting for them. And I'm really enjoying Carol and Antonio building up a romance as well. I'm super curious what this feud between Fede and Antonio is all about - I'm guessing right now that they were both in love with Maria and her choosing Antonio is a big part of it, but it feels like there's more to it. And I really hope Paz is able to rescue Elena so they can be together.
