Assumption Lewis is not the shooter
OK. So they put Lewis in jail for the shooting. What is the end game?
1). The real shooter calls their bluff. Do Angel and Michael eventually say April fools it was not Lewis. I cannot imagine that take the game to the end and issue punishment on Lewis.
2). The shooter cracks and pulls a Jack Ruby. Then try to go back to a "normal" life with two cold blooded murders on their spirit, and do not forget Angel and Michael have a dead Lewis and a shooter to deal with.
3). As above but the shooter is caught and Lewis is dead.
4). As above but shooter stopped and caught
I do not think either end game is good for Lewis.
