This is just a rough guess but 90210 has got about another 12 episodes and Glee hasent hit that many so it will probs be after one of them has finnished unless they Zeigen something else first. oder they could wait to Zeigen season 6 again first like atm all eps are being replayed in the morning (theryreon season 4 atm) however they might just Zeigen season 5 in the morn, wait and bit then but six on earlier in evenings.
That's all just a rough guess really. Hope I helped though. That's just my thoughts. I kinda rambled. Have Du tried watching it on the net?
