This is one of those episodes that serves as a reminder of why this group is together, and that they never forget that.
Stephanie has a night similar to DJ and Thanksgiving. Trying to live life without their mom can sometimes be very sad. Even though Becky and Joey both try to fill in, Stephanie ends up crying, until DJ reminds her that they're blessed in other ways.
The backdrop story is Danny's skewed attempt to clear out the attic of his collection of memories (or junk) so Double J can use it to work out of. He can't bear to part with any of it, and in the end, Jesse puts it all into storage.
It's nice to be reminded, as viewers, that although the lives of these people continue, they never forget the past and what got them to this point. It's also nice that they don't throw it in our faces. What is proper, too much, or too little grieving? It's hard to tell, but the Tanner's pull it off nicely.
