Show incident and tasks in record view

Summary:

I want to display a single incident in Record view and below it al its tasks.

Content (required):

I want to display an incident, say reference number, status, subject, etc. and below this all associated tasks, say task name, status, etc. This is a one to many relationship, so say I have one incident and three tasks. I have a filter on incident reference number and I want to display all incident details and tasks details for this record. Therefore I'm showing it in Record View.

The question is how to display this. Do I need a custom script for this? Process tab? What should I include in it?
