It seems to be a good timing for another TDD session. As we all use a wide variety of languages, it should be up to the pair to chose one language that fits them both.
If you have never done TDD, or do it seldom, it could be good to read up on it, there are many books on the subject, and if there is any particular one that you would like to suggest for your future pair-partners, you can suggest it here. This also goes for youtube videos (there are many out there).
If you would like to, you can practice with a game on top. Like silent pair programming, where you can not speak, but only write code. Or not using your mouse, you are free to suggest any games for you and your partner.
We will end with a retrospective, where you can review your game (if any) and other thoughts.
