[Comment] Continue: true [What it means] 
Makes the player able to continue the game (with their party fully healed) if they lost a battle against this trainer, rather than blacking out and returning to a Poké Center. If this trainer has been set up with rematches by using multiple "Battle" comments, this continue effect will apply to all of those battles.
