In answer to my question about reducing fear when you've taken fear so far that every interaction grows it, phone calls seem to slowly reduce fear at about 2 points per call. Dating did not seem to reduce fear, but did grow the relationship (most interaction where fear is taken that far actually reduces the relationship/love values).
Also, the person that fear impacted showed up wanting a kiss, and if you attempt to kiss her, an exception occurs, so the only solution to move on is to not kiss her. I assume the variables are "abnormal", hence the exception crash.
