Until The End Vs. During: Art of Love Steals Informant

Scenario: It is my turn at a 5-player table and my grand-prey controls an Informant. I play Art of Love to take control of the Informant until the end of the turn. During my turn, the Informant remains ready and no control effects are applied to it other than the text of the two cards in question.

Question: In the next turn (my prey's turn), who has control of the Informant, and did I have a choice in the matter?

It would seem that the Informant should be passed to my predator during my discard phase (according to the text of Informant), presumably breaking the temporary control effect of Art of Love, and that would be the end of it. But if there is no phase in my turn after the discard phase -- in other words, assuming my turn ends during my discard phase -- then I might have the option to order the effects as I please and return control of the Informant to my grand-prey first. That is why I am asking the question.

Thanks!

The Informant cannot act or block. During your unlock phase, any Methuselah who controls a ready Ishtarri may look at your hand. During your discard phase, your predator takes control of the Informant.

Take control of an ally controlled by another Methuselah until the end of your turn.
