My play style is mainly sneaking around and trying to get a headshot every time, and so far its been working quite well for me.
But I noticed that every now and then, my companion will make sarcastic comments that basically imply that I'm a coward for fighting this way (comments such as "Do we really have to do this?").
So far I've seen this happen with Codsworth and Piper (the only companions I have ATM aside from Dogmeat), are these just passing remarks, or do they affect the relationship with the companion? If they do, then who are the companions that dislikes sneak attack?
