No, the reveal that Eren ate his dad comes at the very start of ep 43, when Historia and Rod Reiss touch Eren. I recommend a rewatch of that scene. So Grisha was already a titan shifter, ate Frieda Reiss to steal her power, then turned Eren into a titan and let Eren eat him. This way, he gave Eren both his own powers and Frieda's. As a result, Grisha and Frieda memories lie somewhere in Eren, which is why touching him gave Eren the flashback as well as Historia, who suddenly remembered Frieda.

For the question what episode eren eat his father when he transforms to save armin and mikasa from the cannon almost at the start and have a flashback with his father injecting him was a hint of eren transforming into a titan and eating his father (again sorry for my english)
