But at least in my book, she can't have both - could never have had both if she was an honest person. So in effect she chose the templars every single day. I wish we'd gotten a chance to let her make one final choice, in black and white - choose one or the other, but we didn't get that chance so we just had to assume based on her actions.
I get your perspective, but have to disagree. At least on the love path, early on there was less conflict because all she originally accepted was to stick close to you as a friend (which she already was since childhood). If she was for example an NSA analyst, I'd hardly expect her to be sharing state secrets with her friend. Obviously things are a bit different here since the secrets are more immediately relevant and wrapped up with lies rather than just omissions, but the premise is similar.
The romantic feelings developed afterward, and as we discussed earlier it's unlikely the Templars would have accepted reassigning her to a different task if she tried to separate herself from MC and those feelings. If those romantic feelings are genuine and not just following orders, it'd be easy to justify them to herself as separate from the decision to hide the Templars themselves from MC.
As for making a final choice, it wouldn't surprise me if something like that is upcoming now that MC has spent time with the elves and potentially had someone they cared about (as a friend or otherwise) killed by the Templars.
And yet it wasn't really her who uncovered what she is, if not for the attempt on MC's life she would happily follow her oaths until the end of times.
Possibly, but we can't really know for certain. I can see potential other triggers that could have forced a realization, like MC proposing or something. It's all speculative of course.
She wants to sit on two different chairs at once.
The moment she realised that what she is doing is wrong, she should have taken a stance.
She's a big girl, she kills people for a living.
Yes, she did want to keep both going in the status quo as she admits on the love path. The longer the lie went on, the harder it became to come clean because of fear that MC wouldn't forgive her. Obviously that doesn't excuse it, but it's a feeling I can understand.
As for killing people for a living, that's a vastly different skill set then emotional intelligence and relationship communication, heh.
