I think it's best to err on the side of caution and not mention any future events, even obliquely. That's especially true this season. There's always the spoiler thread for further discussion.
This episode was just average by Game of Thrones
standards in my opinion. I enjoyed the introduction of the new characters, but this was another table-setting episode and one that moved a bit slower than the season premiere and didn't have the wow factor of some of the premiere's scenes. It was still an enjoyable episode, though.
