A perfect grasp on the language definitely wasn't necessary for Renne to get his point across. The power of the words penetrates Billy's head and echoes across his thoughts.

Billy thinks his impish blue friend might be singing for comrades long lost, and feels a pang of sadness for them. At the same time, he hears a message of togetherness: perhaps he'd managed to make his point the other day that everyone on the ship was in the same boat, and that not all humans wanted to hurt.

Renne, you have a human admirer cheering his lungs out for you, and you'll soon find that it's traceable to Bee's scent.
