Although their group members are much better now, they still have to think of ways to kill zombies that have powers. Moreover, before they decided to go up to the first floor, they had to kill a zombie that could emit poisonous smoke.
If they don't kill the zombies, it's useless for them to go up again because, in the end, they will be poisoned again like before.
Cassian and the others were discussing this when Theodore woke up earlier. Once Theodore was there, they could continue the discussion again; they had to find a solution to this problem.
"We must think of a way to find the zombies that can emit toxic fumes," Cassian said in a huff. He thought about going alone but couldn't handle the zombies' toxic fumes.
"But we all know that there are many zombies there. We also can't distinguish between zombies with powers and ordinary zombies."
