Unsurprisingly, there was no love lost between Nina and Ava.

She was completely gutted when he murdered her adult daughter Kiki Jerome (Hayley Erin) on Thanksgiving 2018.

While dealing with her grief, visions of her dead daughter began torturing Ava.

Ava believed she was suffering a nervous breakdown and checked herself into the infamous psychiatric facility Shadybrook.

He and Nikolas Cassadine, along with various accomplices, were both determined to get their hands on it.

Luckily Nikolas was there to rescue her and the two crashed the ceremony (viaSoaps).

Thus began a friendship between the two women that outweighed any of their past animosity.
