Mike and Alison have to quickly adapt to hosting a children's party, and one of the ghosts moves on.
I had a feeling that when a ghost moved on in a recent episode that it was brought in to serve a purpose, to allow one of the cast members to leave, I wasn't expecting it to be quite so soon after, and quite so early into the episode, a shame she didn't have one last hurrah.
I think this has been the best episode so far in this series, it had some very amusing moments, and also sone wonderfully moving ones too, it was interesting to see how the ghosts dealt with loss, it's just a really fascinating concept, the dearly departed themselves dealing with loss.
I thought it was Robin that provided the most special moments, and that scene at the end with the stars was quite magical.
All in all, this was excellent, 9/10.
