I do agree that Liz would know if Jason was off.

Do we think the Jason who was shot and dumped in the harbor was faux Jason?
He was no longer needed.
So, he was taken out.

Liz was rejected by Jason.
She messed with Danny's paternity test.

She is heartbroken over Jason.

At the time, I wondered if we were dealing with a faux Liz.

I think she would be very hesitant where Jason is concerned.

I want the real Jason to return.
However, didn't Victor tell Robin, Jason was pulled from the harbor alive?

So, we may be picking up where we left off.

Speculation suggests, Sam will step aside for Silas and Nina.
So, she will be ripe for a spouse return of her own.

I would like to see Patrick and Liz be the people to provide him medical care and return him to his old self again.
