I believe that ALIE happened upon a threat by following her directive to make life better for humans. She finds dangers and adds them to her calculations regarding what steps to take to ensure the safety of people.

But if that's the case, Bell handcuffed her for the same reason, right? Sure he was angry at her, but it didn't mean he wanted anything bad to happen to her in the same way Lexa kidnapped her because Clarke is good at being in danger. Like Bellamy's reasoning for doing it was to "keep her out of trouble".

Well, Roan did stab Bellamy in the leg early in the season when Bell was trying to rescue Clarke, so…lol, I was actually amused to see him shoot the Ice King because sure, it was a good test, but to me, it was obvious payback…and almost seemed like territory marking/pissing contest honestly. Bellamy has been either…
