I'm not sure exactly as I haven't read it. But generally, it might be about the adventures or misadventures of characters who are considered 'wicked' in some sense, perhaps showing their continuous struggles without rest.
Well, considering the title, the main characters might be characters who are morally grey. They could be thieves, con - artists or even ex - criminals trying to survive in a world that doesn't give them a break. It's also possible that there are some sort of supernatural elements involved, and the main characters are beings that are damned or cursed, and thus have 'no rest' in their existence.
Another theme might be the consequences of one's actions. If the characters are 'wicked', they are probably dealing with the fallout of their bad deeds, which is why they can't rest. For example, they might be on the run from justice or facing revenge from those they've wronged. Also, competition could be a theme. If it's a game - like situation, they are competing against others in a high - pressure environment where resting means losing.
In this type of fanfiction, one common theme could be the power of love over darkness. The 'wicked' aspect might represent the dark side of a character or a situation, and 'love is kind' shows that love has the ability to be gentle yet strong enough to combat that darkness. Also, forgiveness might be a theme. If a character is 'wicked', love could lead to them being forgiven by others or themselves.
Some fanfictions might focus on the emotional aftermath for Sam and Dean. Maybe Sam is more affected by what happened than he let on in the actual episode, and the fanfiction could explore his inner turmoil. Also, there could be plotlines where other hunters get involved in the events that followed 'No Rest for the Wicked' and how their presence changes the dynamic between Sam and Dean.
