What specific template file is used by Q&A with twentythirteen theme?

I'm using a child theme for twentythirteen with specific conditional formatting on page.php, footer.php, and sidebar-main.php and all that works for my other pages/posts. But with the Q&A plugin, something is amiss. My best guess is that it is picking up some other twentythirteen (parent/default) file that I have not modified. But I can't tell which one. Can you let me know which template files when using the twentythirteen theme your Q&A plugin uses? Thanks so much.
