Perhaps you'll be able to bribe your way out of prison?
That, or...
-Ways to actually wait it out
-Having people break you out. Lets say you've worked your way up to the highest ranking in the Dark Brotherhood.
-Alternate ways to break out (Ex: Not walking out the front door.)
-Talk to the jail guard and get him to like you
-Talk with other inmates to work out a plan to break out
