I cut to the chase and say that this was a good episode apart from one part being telegraphed and one part extraneous.
The telegraphed part is of course Big Mac thinking (mistakenly) that Sugar Belle is in Ponyville to break up with him. The extraneous part is the whole thing with the CMC and thinking Sweetie Belle may have a secret admirer after the postal mix-up. I guess there needed to be a B-plot in this story and something else for Big Mac to bounce off of.
Now let’s get to the good parts. Discord is actually making an effort to be helpful and cheer up Big Mac. The part with “Skelanor” was quite humorous. Spike was good in this one too to tie in with “guys’ night”.
Long story short, Sugar Belle is taking a part-time apprenticeship with Mrs. Cake while her cousin is running the bakery in Starlight’s old village on weekends (to be on his own for once apparently). Of course, Discord “stalled” Sugar Belle so that Big Mac can square things away with her.
So overall, a better effort from last week apart from the telegraphed mix-ups and the extraneous portion with the CMC.
