What kind of information are you trying to show? There are different templates that are called when showing a thread and different plugin hook locations for the different templates.

The gist of it all is that you write a plugin that hooks some location(Usually the hook location is associated with the template you want to add your variable to). In your plug-in you fill your variable with data(html) and then edit the right template and just place your variable( ex. $yourvariablename) where you want it displayed.
