I'm going to guess that his daughter is still young at this point in time, he climbed up the wrong tower in his search for her, and found Rapunzel. She's showing him a box in the picture, so perhaps she knows about his situation and asks him to help her retrieve something from the witch. Maybe he failed and got his heart poisoned. If she's Tremaine, maybe he abandoned the mission to go off and find his daughter instead. She suggested he did something to her but she acted more annoyed than angry when she mentioned it.
