Which ones specifically?

It would depend. If I read correctly, Hestia, Henrietta, and Pastille conflict for leadership of the Circhester Gym. Henrietta less so than Hestia and Pastille because which gym she occupies is more vague.

Pastille's background is that he battled for leadership for the Circhester Gym while Hestia started a fire type gym in Circhester. Depending on context such as two gyms existing in one town or there can only be one gym, I would most likely have to change my background.
