Help me figure out where we are in Game of Thrones (some spoilers)

I'm trying to keep spoilers to a minimum for myself - so don't want to read every episode description.

We stopped watching, and was behind at that, about a year ago. I am not sure if it was the previous season, or the one before that.

But here is what I vaguely remember...

Spoiler:

Arya is on some island washing dead people. Tyrion is on a boat with someone, he was kidnapped??? But then rekidnapped??? And they were attacked by the stone people - and the other person got scratched??? Jaime has gone to get his daughterniece from wherever she is - I think he and his buddy were attacked, but don't remember if that was resolved.

So, do you have any idea about what season/episode I'm on? If I could at least get close, I wouldn't have to read too many descriptions and run the risk of a spoiler.
