They either got married या he didnt get married at all cause in the proimse Suki was Zuko's bodyguard along with Ty Lee and who else would marry Sokka. not many people can handle his sarcasm and witty ness
Maybe not, Suki is now Zuko's bodyguard, and as much as I hate it, Sokka might get cut out of the picture. Don't hate me, hate the guy who wrote all this cr*p.
