Carver nodded and followed along, nodding and listening contentedly as Behemoth showed him the ropes of pumpkin farming. Again. 

One of his oldest friends, the caretaker of the pumpkin fields had taught him everything he knew about the growing and harvesting of the plants over the decades, and Carver never quite tired of hearing the simple but earnest words and seeing the happiness Behemoth clearly felt at having someone to share it with. The big monster had the same passion for pumpkin farming as the witches had for potion brewing and Finkelsteins had for science. Unlike the witches and the Finkelsteins, however, Behemoth was quieter and sweeter about it; Carver never felt like he was being lectured, even when that's what was technically happening.

There was of course the secondary bonus that Carver got to rest his "automaton" voice for a while. It helped sell the bit, but even he found it annoying after a while.
