Answer 1

Jonah is experiencing and showing an emotion.
When Jonah is experiencing something he likes (like being in a warm bath), he will start showing an emotion of happiness. Whenever a person is experiencing a positive event they are fond of, they are likely to exhibit a positive emotion related to that event, and Jonah is no different.
