Yikes. That episode did Venice no favours as a tourist destination. So grey and dingy and sad. That being said I would still go there for a day or two for the experience of it.
Josh was incredibly shady during this episode but I still think he makes hometowns and I honestly can't see anyone but Nick beating him at the end. Unless a dark horse shows up in the next few weeks, it seems all but determined that it'll be Nick and Josh final two. They're the only ones she's had very obvious chemistry with. She likes Brian's kisses but he's much too wishy-washy for her. Marcus is so, so corny - I can't see him lasting much longer. The farmer is dull. Dylan got lucky with that pity rose on his one on one date.
I never in a million years would have thought that Nick would be Andi's type. I find them interesting despite being baffled by them as a pair. I think what might work against him is that he's got that nerdy, city vibe about him that might not fly in the hometown dates. I don't think he's alpha enough for her family.
