Update : I tried it. I picked "I swear". I don't like it. I think Nettie just triggers my inner teenager xD Don't know yet what my final decision will be on this since both answers don't resonate with me. Oh well. Between now and the full release of the game I guess I have time to think about it.
I love the implication of having:
1. I swear
2. [Lie] I swear
And your companions psychically knowing right then and there on the spot which one you meant. Because of the tadpole.
Yes, that or a deception check (as suggested by The_Red_Queen) would be swell
Now a bit of fantasising:
I think it would be cool if game kept track of promises we make and break. Perhaps one of our companions would be reluctant to trust us as he or she witnessed us lying to someone. Or maybe someone is easier convinced by our words as we are well know to stay true to what we say.
I like that idea
Might be hard to implement but I like it.
