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.
