Yeah, it's hard to pick only one when the other immediately bursts into tears and mostly disappears from then on. (Also, when trying out Korra only, Pema telling you she thinks you chose wrong. ) I am sorry, bundle of pixels and code!100% you still end up marrying one or the other, it seems then the other one doesn't show up on Ember Island. BTW - I don't advise you to try ... Jinora's (in my case) face when the MC got married to Korra - I immediately went back to the old saves and tried to get a "perfect ending".
