When Evan comes clean, I think it might be nice for him to let Conner's family know that the final interaction between the two of them included a genuine, if very brief, act of kindness on Conner's part. This might give some comfort to them, since apparently they never saw any warmth or goodness in him. This could also give Conner's family some reason to believe that everything that followed his death was based on something, however small, and perhaps provide more of a motive for not exposing Evan's fraud. It would also simply be a kind thing for Evan to do at that point, making his redemption slightly more plausible.
