It was during some kind of verbal game and Muraki (AKA Silver, the eponymous doctor for our chat) used fellatio in his tongue twister or whatever it was. Kazu and I think Sunny we're wondering what it meant in the endgame and instead of bothering Muraki for a definition Kazu decided to figure it out on his own. "Fellatio" sounded like "fellowship" and Muraki is a troll and didn't correct them.

Tell me about Drift and Echo!
