My totally speculative guess for why he's "gloating" is that during his "off the record" settlement conference, he interpreted some comments from the prosecution as them not intending to bring further charges. That's just my guess, though, and it probably doesn't mean they won't bring more charges related to Rekieta's access to Aaron's Google account, but only within his current criminal case.
But I don't know... I just imagine it might be similar to when the State said in their letter that the current case had no victims involved, and he interpreted that as an extremely positive sign.
