The interview will be on the tuesday podcast wich will be up in about half an hour.
ETA: It's up now.
ETA2: SPOILER WARNING: Aaron talks about Earth from the mid-season finale. It's the same thing he mentioned in the Dreamwatch article. From the sounds of it, I don't think he realised he was giving out a spoiler. Skip past time stamp 10:20 - 11:20 to miss the spoiler. (thanks meshel73)
