Fool's Links
Fool is currently travelling with Castiel and keeping him company on his space travels, telling jokes and anecdotes of different levels of crappyness. Fool likes Cas, altho he is quite moody a lot of the times, but Fool deals with it by simply ignoring this aspect of Cas' persona.
Cas is quite glad to have Fool as his company, actually. Although he feels mildly weird due to basically having a personal jester as his buddy. But he doesn't mind if Fool sticks around as long as he's not a bother.
