"Suite and Sour"
- Arson, Murder, and Jaywalking: After all the hijinx that the Loud siblings did that caused tons of property damage, the real reason the Louds got kicked out of the hotel was due to Mr. and Mrs. Loud skinny dipping in the pool after hours.
- Bad "Bad Acting": During the play that the Loud children make in order to convince their parents not to make them stay at their Aunt Ruth, Luna says her dialogue in a dull and mispronouncing tone.
- Children Are Innocent: Rita and Lynn Sr. vow only to tell the kids why they got kicked out of the hotel when they "get older". This assumedly extends to the older children (Lincoln, Lynn, Luan, Luna, Leni, and Lori), who should realistically know about sex.

- Continuity Nod: It appears the kids haven't learned their lesson about eavesdropping, and they still dread going to Aunt Ruth's house.

- Unplanned Staycation: At the end of "Suite and Sour", the Louds get kicked out of a hotel. The kids, thinking it was their fault because most of them had misbehaved, set the house up like a resort and leave for their great-aunt Ruth's house so their parents can get the vacation they want.
