how many আরো times do we see oz in the প্রদর্শনী after he left?

Actually, we see Oz only in another ep, which is "New Moon Rising" (Btvs 4x19), when he comes back to Sunnydale just to know about the rising relationship between Willow and Tara and be caught from the Initiative.
দ্বারা the way, the last time we see him is in the season finale "Restless" (Btvs 4x22) in Willow's dream.
