he definitely shouldn't have his career ruined if it's just her word against his
It isn't even a toss up at this point. He's provided evidence suggesting that she was still seeking him, even months later. So, unless she provides evidence of her own, he should get all of his usual show bookings back on track. I say should though because there's still a chance some Hollywood types blacklist him for a time anyway under the 'better to ruin an innocent man's life here and there than discourage other women from speaking' banner. They're allowed to be sexist in that way.
He needs to sue, no really I just want to see her evidence ---
