Links for Season 6 ep 16?

Why are there no links up for the latest episode??

Izzy and Alex!

What's going on with Izzy and Alex?? Alex goes off sleeping with Lexie (even if it's without "feelings") but he should have worked it out by now with Izzy!! They ARE married!!! I know Katherine Heigl is busy with her personal life but seriously can they at least tell us where Izzy is or when she's coming back!? I really want them together, think they are an amazing couple...a bit immature :p ....but great couple!!!! I really hope they end up together! Does anybody know details??
