Rebecca Herbst has been incredible in the role of Elizabeth Webber for the last 25 years.
However, the writing provided for her character and the choices Elizabeth makes are often atrocious.
Franco and Elizabeth were an example of a relationship that developed organically.

They had hilarious banter between them, and he worked hard to establish relationships with each of her boys.
They had a mutual enemy (aka Peter) in common, and it masqueraded as romantic feelings.
That’s not love, that’s convenience.

It was a lot of start and stop with very little fanfare.
Resulting from their lack of chemistry, there have never really been any sparks between the pair.
There have never been any monumental personal moments between them, either.

The biggest problem began when Elizabeth had memory problems and would black out randomly.
Any time Elizabeth appeared to be going through something, Finn was too willing to spill it all.
The secrets and lies caused several problems between them and became a pattern for the rest of their relationship.

Once Finn learned about this, he and Elizabeth took a (sensible) break from each other.
The couple took some time away from each other after this reveal, but ultimatelyFinn and Elizabeth reunited.
Of course, they started out as just friends, but their path was obvious.
