Ironically, blue shirt here is showing that off in reverse: refusing to do due diligence, simply ghosting red shirt with no explanation whatsoever, against the explicit advice of green shirt. Anyone who ghosts may even be doing other people a favor to warn them to stay away from their own toxicity.

Irl caveats may apply ofc - e.g. definitely get far away from an abusive relationship and if need be enter witness protection type of scenarios, but here we are talking more casual circumstances.
