If it craves the empathic bond it shares with its trainer, then there's some sort of mental complex at work in both the trainer and the Gardevoir. This could also apply to a jaded/bored Yanderevoir that's addicted to the particular 'feels' of its supposed master.
If the Gardevoir is more attached to a concept (duty, trainer's former image, battle, etc.) then there will need to be some source of reciprocation that isn't from the trainer (ex: Gard's subconscious, local community, broader society). This would gradually make the Gardevoir more individualistic and more of an attention-seeker, eventually breaking away on its own.
