Putting the comments on the home-page

I want to modify the appearance of my WP site so that the comments on an article appear immediately after the article on the home page.

Normally (as you know) you need to click on the post to see the comments for that post. The blogger wants to make it so that this is not necessary: She wants it so that people can simply scroll through one very long page.

How might I go about this? I’m using a K2 theme – there must be a file which controls the appearance of the stuff which comes after the main post?
