Talon Question

How will Talon's past affect his ability to perform in possible hypothetical relationships with other people etc etc? For example, let's say something between Talon and Quinn gets on in the near future, will his past actions affect his relationship? For instance, he has killed a lot of people in his career and continues to but I am more particularly concerned about something that "may" haunt him time from time and that is the murder of Kavyn. Now Kavyn was very close to him, a very close friend and he was backstabbed. So my question is, will he be haunted by Kavyn's murder throughout his life since it was borderline "murder" or will he forget it and move on? Can he get into a relationship with another person without his past preventing him to? Because let's face it, the last person that was close to him in a relationship was Kavyn and he was backstabbed and killed simply because he was deemed "weak and a liability." What is preventing Talon to adopt this very same ideology on future relationships with people he has? Like lets say a relationship with Quinn? It seems scary on paper. But then again this is all hypothetical, they are more based on IF it happens.
