So: the only difference between single player and multiplayer is that in the latter someone can join my game and impersonate my second character for me (meaning that if no one joins it'll be totally like playing single player)?
Or will he 'replace' my second character with one of his?
Can I eventually turn a single player campaign into a multiplayer one and turn it back to single player?
