Hey I have a question, is the person that gets picked at the end of an expedition RNG or can I affect the choice somehow?
Edit: Never mind, it think i discovered how it works.
Scouting the rival splits the party in the next map. Companions get taken if adjacent to the rival, otherwise Piper gets taken and you play as the companion. Scouting with 1 open tile around the target will guarantee that Piper is chosen, while scouting with 2-4 guarantees that his companion is chosen. Only your final scouting action counts and as of v2 spells can also trigger this interaction.
