Robin Hood - S2-E3
Stupidity: Nora fled to the Ludds at the end of season one because someone was trying to kill her because she was getting close to what went on. Here they suggest she goes back to Horizen to work undercover, and she just...goes. Nobody seems worried that she'll be exposed and vulnerable.
Dinner Party - S2-E2
Stupidity: Nathan sees who he thinks is Nora at the Dinner Party - despite her boss using her avatar once before, so he knows not to assume it's her, especially given she's been missing for weeks. He's completely thrown by her unusual behaviour, and it doesn't even occur to him it might be someone else.
Stupidity: Nora's dad believes in heaven and doesn't want to upload himself, because he wants to be reunited with his wife. When visiting Lakeview, he tells Nathan that Nathan's soul went to "real heaven," so he's just talking to a simulation. Which means there's no reason he can't upload himself. His soul will go to real heaven like he wants to, and he can leave a simulation behind for his daughter to be with. Everyone would be happy, but nobody makes that argument.
