I strongly disagree. The writers were letting us experience what Carol and Manousos were doing and feeling when she was isolated and he was making his way north.
We got to see Carol go from enjoying having her requests granted (like her dinner at the restaurant) to breaking down from the lack of human contact. And we saw Manousos eschew any company or assistance, to the detriment of his health, all in service of his desire to save the world.
In the Pluribus podcast, the actor who plays Manousos said that Carol has all the material things she needs, but is empty, while his character has almost nothing, but is filled with purpose.
I don’t think the contrast between them would have been shown as well had the story moved along more quickly. The pace also made me enjoy the humorous aspects of Carol’s journey more.
I’m looking forward to seeing what happens if and when they eventually connect.
