Hm... I don't know what age group you're aiming the cartoon at, but rape is a... heavy thing to include, even if only by implication. You should be very, very careful with that if, lest you're accused of taking the subject too lightly.
As for your three options - depends what exactly you want to accomplish. If you want to spend an entire episode on the plot of breaking the parents out - essentially, heist movie in miniature - then take option number 1. If you want to deal with the imprisonment problem as kind of afterthought (perhaps after spending the episode aquiring the money?), pick number 2. If you want to show your character as a, frankly, somewhat terrifying person (or an excellent actor, who's sorta scary nonetheless), you should probably use number 3.
PS - you link tropes by writing them in CamelCase.
Rejoice!
For this cartoon I'm working on, there's a subplot about the parents and sister of a main character being in prison, after being falsely accused of murdering the main character. So, the first part of the subplot is the hero spending a day with his mother and sister who he gets out of prison. I am at a crossroads here, and I have three ideas on how the break-in should go down. 1. The hero slips into prison, breaks them out, and sneaks them outside. 2. The warden is very corrupt, and the hero bribes/blackmails him into letting him "buy" the two convicts he wants. Probably the best for fridge logic. (Sorry, I don't know how to link to tropes.) 3. He breaks into prison under a guise of "cleansing society," and he declares his intention to kill the people he wants to break out. The character drags his mother and sister out, to "execute them." After spending sometime with them, he attempts a fake execution when he's nearly caught.
Also, I have decided for the main character to get in a fight, and maybe murder, the prison guard who's been raping his mother. Given I want this to be a cartoon, the rape will be hinted at. I do not know which option to choose, and I like the three of them equally. Which of the three options should happen?
