Warning: This article contains spoilers about Thursdays episode ofGrey’s Anatomy.

He suddenly reunites with Izzie who secretly had his kids five years ago?!

It was a stretch, even forGrey’s, though admittedly not nearly as far-fetched as ghost sex.

(In the end, he lent his voice to the hour, but that was it.)

A character fans loved.

A character fans watched grow.

He hadn’t been “Evil Spawn” in quite some time.

So, the writers had a choice to make.

In the end, they decided the answer to that question was no.

And here’s why I think they made the right call.

Grey’s Anatomyhas seen many beloved characters come and go at this point.

Izzie, Cristina, and Callie all left.

George, Derek, and Lexie all died.

And that’s just a handful of exits, some of which worked much better than others.

(George’s death was tragic but epic!

Derek’s sucked.)

It would’ve left viewers feeling empty and angry.

That’s not a proper end to a character.

Then you have to look at the relationships Alex has built and built recently.

He and Jojusttied the knot officially!

He’s Meredith’s person!

There are some things that are simply too dark, even forGrey’s Anatomy.

And killing Alex Karev would’ve been too dark.

Is giving Alex some weird happily-ever-after on a farm the answer?

But I do know that letting Alex live was the right call.
