Ruffnut and Tuffnut's Relationship

"We can go back to our normal life: Two adult siblings living in familial harmony, spending every moment together, united as one living, breathing being that tries relentlessly to invoke physical harm on the other."

- Tuff in "The Wings of War, Part 2"

The Twins have a complex yet rather typical relationship for fraternal twins. As kids, they always seem to be physically fighting and finding glee in the other's pain. As time goes on, however, they turn toward apathy toward each other, emotional manipulation, and eventually mature into admitting outwardly that they're inseparable and love each other dearly, despite all the fighting.
