Attacking Junius or Bibius from far enough away doesn't result in combat. Killing this way only nets XP if both are killed. Killing Bibius first and walking up to Junius results in a dead Bibius speaking. Killing Junius first results in a silent Bibius. It's possible to have 2 dialogues about killing innocents. 1 for killing Bibius and another when you kill Junius.
