The boat is floating fairly lazily towards the pier, making slow and deliberate progress towards them. If someone's at the helm, they aren't visible from here. But it's certainly not going fast.

After several moments, they turn back towards Terrence where he's sitting and they give him a look. Whatever they're thinking isn't shown on their face, instead there's just this gentle curiosity as they look him over. He hadn't attacked. He'd listened. And now they were going to leave him here.

They give a small wave of their hand as a farewell, thanks for not being horrible, Terrence.

And then they start walking towards the end of the pier again. The boat isn't here, so they can only go so far.
