Hacer las paces, “to make the peace,” to reconcile. Hacer borrón y cuenta nueva, “to erase and open a new account.” El Imparcial explains that it means “olvidar errores o deudas pasadas y comenzar de nuevo sin rencores” (to forget past mistakes or debts and start again without resentment). Lo pasado, pasado, “what is past is past.” It is also the title of a song by Juan Gabriel, recorded by José José in the late 1970s.
