Forum:KB:Clone Wars timeline question

Anakin is said to get is knighthood in 19ABY, but he gets Ahsoka Tano in 22ABY, when he is still a padawan to Obi Wan. So am I missing something as to why Anakin got a Padawan when he was still one? Or was he a special case? Mini-mitch 21:44, September 15, 2010 (UTC)
