Sister's Hug:

Not everyone can not work, other characters, the only one of all can work is Kiara because she has a heart of love, also Diana has a heart of Hate, and both need love, and Diana will not be able to resist the hug, but sometimes she can stay away.

Diana hates the memory when she was little, she can't stop forever.

Diana just defeated Superboy, and then Demonlings released her head and will never see childhood memories again.
