So, I was going to start my own thread about at which point in each conversation you start making relationship decisions that are irrevocable (currently Risha is at 10k and Akaavi around 5k and each is starting to talk seriously about what I want regarding a relationship).
Any specific spoiler-heavy feedback is greatly appreciated, I'm already gathering that I can do whatever I want off the ship with NPCs (especially if I have my fellow male Companions out instead of Risha or Akaavi) and even if "busted" you can apparently smooth things over so that's not my real quandary here.
Instead, I truly need to know at which point BioWare (like in ME2) "locks" me into one relationship over the other so I can continue carefully progressing with both until I reach that conversational "fork in the road" where I must then forever pick one partner or the other.
In closing, in summary, I basically have quest icons above both their heads currently while on my ship (I am level 48 and now have all 5 true Companions) and each is about to move past the [flirt] "Sure, I like you" stage and onto serious relationship discussions. I've decided to put both on pause and be safer than sorry by posting on the Forums instead for further guidance before I'm officially forced to pick (given that it's likely I can't have both, which sucks). I will ultimately choose Risha since she's the all around better RP/class fit versus Akaavi, although Akaavi seems a better "soul mate" but oh well!
