It was a theory and nothing more. With 23 episode titles known and 11 more still unknown, it is a very slim chance that the above theory will happen due to the current focus of the season being on Pops. There is still a chance of the possible cameo appearance(s) towards the end, but other that that, I would not count on there being an episode focusing on those two alone.
