I realise you are being somewhat flippant, but it is still sad, because (among other reasons) it appears that Liz Everett misunderstood her father's theory.
If the theory of quantum immortality is true, then while from our perspective, Hugh Everett died from a heart attack in 1982, from his own perspective, he's living on in some other branch of the multiverse in which he somehow survived that heart attack. Similarly, while from our perspective, his daughter Liz died from suicide in 1996, from her own perspective, she's living on in some other branch of the multiverse in which she somehow survived that suicide attempt. Indeed, if the theory is true, then no matter how many times 1996 Liz tries to commit suicide, from her own viewpoint she will never succeed – but she never gets to see her father again either – he's living on in a different branch of the multiverse from her, one which diverged from hers all the way back in 1982. And even that other Liz, whose father didn't die in 1982, is doomed to eventually watch her father die, and her father to watch her die, even as both go on living forever, trapped in different branches.
Quantum immortality promises us a somewhat bleak afterlife in which we all live forever, but none of us ever get to see each other again. Eternal loneliness is our universal doom.
The only way in which she actually could see her father again, would be if quantum immortality is false, but some other afterlife theory is true instead.
