The Recess!! I owe you 1. How long does the 1 last though?

This show is about loyalty. If you have been a partner in crime(any type of crime, not even a real crime but, ya know) before and your partner looked out for you and now things have changed and you have changed but they are still there what do you do? How long can you hold it down for them? You have moved on but they need a lot more help. How do you deal with it?
