ELLE TRIEDMAN:We came to it pretty quickly.

This obviously paints Isabella in a very bad light since Lisa’s death is very similar to Luke’s.

Did that play into why Isabella has been keeping this a secret this whole time?

Some of that will be revealed in the next few episodes.

One thing to really keep in mind is Lisa died in February and Isabella comes to Chatham in June.

That’s the fun thing aboutCruel Summer there’s always at least two sides to everything, sometimes more.

Should we be suspicious about the fact that Lisa and Luke died in very similar ways?

It is not a coincidence.

They both drowned, but the circumstances around their deaths will prove to be quite different.

What else are we going to learn about Lisa’s death and Isabella’s potential guilt about what happened?

We will learn that the sheriff is looking into it.

It is already very clear that Isabella has an attorney on speed dial, a family fixer.

If you look at the news article that Trevor sent with the letter, it’s a drowning.

You will hear more about it, but it certainly provides and confirms this undercurrent of distrust for Megan.

How does this reveal impact Megan and Isabella’s friendship moving forward?

They’re very much estranged in the third timeline.

They’re physically living on the same property but not really interacting.

For Megan, it just means she can’t trust a word that Isabella says.

It makes her question everything.

You start questioning yourself and it creates even more distance for Megan because she’s very self-protective.

You actually will see them working in sync again.

Desperate times call for desperate measures sometimes.

It’s always hard to recapture that first love of a friendship, but you will see.

This is a huge newsflash for everybody.

You will catch up in real time to the discovery of the pregnancy on Megan’s end.

We’ve also seen Megan hiding a bloody sheet in the trash.

How is that going to come into play moving forward?

It will be discovered.

Those sheets it’s not the last we’ve seen of them.

They’re like Chekhov’s gun.

It’s something we talked a great deal about.

I watched season 1 as a fan and they stuck the landing.

That was a pretty great ending.

When I came on, I wanted to not repeat anything and start fresh.

I’m very happy with our ending as well.
