“He’s a great presence and a great energy.

But Clyde won’t be the only challenge Liz has to face.

There’s also the effects of the intellect-enhancing drug she’s inhaled lately.

“I need your mind, Allie, to help me stop this alien.”

Drama aside, fans can also expect some happiness from the show’s farewell.

“We talked a lot about where we wanted to end,” Hollier says.

“The world is a very different place than what it was in season 1 and season 2.

We’re cognizant of what was going on outside our windows.

That was the goal with seasons 3 and 4.”

One bit of happiness?
