According to the Oxford Dictionary, present simple is used to describe the story in novels, but does that also apply to actions being done by characters at a precise moment? Now I know that present continuous is used to talk about actions happening at the moment, so why shouldn't that apply to actions in books and films as well? Unfortunately, the examples I found in the Oxford Dictionary didn't help much to answer my question since they all refer to events rather than current actions.

She, on the other hand, develops an immensely strong bond with Heathcliff, which becomes an all-consuming love. Upon her father's death, Hindley becomes the head of the family and forces Heathcliff to assume the position of a sevant. [...]
What if the characters were, for example, talking and laughing about something at a very precise moment, which tense would I have to use to describe that?
