Reeves had absolutely no reason to betray the Survey Corps. If he opposed the Survey Corps, at best his company would be ruined, at worst he would lose his head (which happened anyway). I think Reeves Jr., if not caught, could possibly help the Survey Corps sincerly now, since he witnessed how "nice" the Survey Corps and Captain Levi is, compared to "Captain Ackerman".
