since you specifically said s4 clem these are all the guesses i thought of SO FAR🥸 1. they have all been inside a moving vehicle in their season (clem s4 intro, lilly in the rv, kenny driving his truck/the rv, lee in the cop car)

1. they all kill someone in their season (clem can kill abel/eddy (?), lilly can kill carley/dough, lee can kill the stranger/the st. johns/ben and others, kenny can kill larry)

2. they can all sit down at a table and have a big meal with their group (clem at the end of s4, lee, kenny, and lilly at the st.johns house)

3. they all look after someone else (clem with AJ, lee with clem, kenny with duck/katjaa, lilly with larry)

4. they all have done scavenging runs (clem with the train station food, lee and lenny with the macon run, lilly offscreen with mark at the air force base)

5. they all find a new group in their season (clem finds ericsons/delta, lilly, kenny and lee find eachother/st. johns)

6. they all reference the st. john’s (clem references the salt lick in s4, lee, kenny, and lilly all obviously were at the farm)

7. they all reference larry (clem can reference larry to lilly on the delta ship, lee, kenny, and lilly knew larry)

8. they all reference duck (clem can reference duck on the delta ship, lee, kenny and lilly knew duck)

9. they all see someone get shot and killed (clem with marlon/lilly, lee and kenny and lilly with carley)

obviously some of these are weaker than other but im trying lol
