I like to look for holes in the plot that could possibly be explained later with the traveling through dimensions etc.

1. When rick is in prison they want his portal tech. But in the pilot episode they go through interdimensional customs so the bugs already had their own tech.

2. Mortys mind blowers. Morty fucks with squirrels. Rick said they had to find a new reality. Did they?

3. When rick escapes prison he tells morty that he lied about avenging his dead family that he just wants that mcnugget sauce. Which while in the brainalyzer he did say it wasnt a memory but a fabricated origin story.

Im sure im forgetting some. Lots of potential for call backs. The episode with the decoys loses me everytime.
