But I thought that the Trix were bonded otherwise how could summoning the most powerful animals free the Trix. But again I think you are right. They may own them and not have bonded with them cause the fairy animals were introduced in season 7 only as I think they were stuck in the middle ages and were brought back thanks to the Winx and we had never seen them with Roxy too if they had existed in the present (My theory).

You can watch season 7 here: Winx Club Season 7. I watched most of it here or on dailymotion.
