No, the middle node cannot change data. It can, however, randomly cut out and drop circuits, connections, or drop off the face of the earth entirely. That is probably what was happening to him. The middle node essentially knows nothing (other than who the entry and exit nodes are), so there would be no benefit to doing so either.
