Current mood: agonising about who or what Will Forte meant when he said
“another old friend makes an extended appearance” this season

(spoilers ahead!) I just looked at the official press releases for the next few episodes and 4×14 has this tidbit:

Meanwhile, Carol grows suspicious that a new stranger could be living nearby

And then comes 4×15, which has the interesting and far more serious-sounding than usual title of “Designated Survivors”:

Tandy wakes up to a shocking discovery that is positive for everyone in the group, but it throws Todd into a spiral

…it’s gotta be Mike, right? On the other hand it does say Designated SurvivorS so maybe my pipe dream of Mike returning hooked up with an actually not-dead Lewis might come true after all but probably not.
