I got a headcanon... After the end of the "Homeworld" arc, Lapis tried to restore her friendship with Peridot, she did like Peridot at the beginning of their friendship. Lapis kept warning that she was leaving and when she would return. She asked how Peridot was doing and if she needed anything. Lapis tried very hard to regain Peri's trust 馃ス
(P.S sorry, just sad Lapidot edits have a bad effect on me)
