The current condition of their group members was exceptionally grave after they were affected by the poisonous purple smoke. They had no supplies to cure the poison, and even Theodore couldn't do anything for them.
They could only hope that the poison they inhaled did not harm their bodies too much. They did not bring the necessary medicines to treat the poison; right now, they needed help from someone with healing powers.
However, it would be impossible for them to find such a person because there weren't a few people with this kind of power.
The people in the back only inhaled a little smoke, so they were unaffected by the poison.
Theodore and those people ended up helping those directly affected and inhaled quite a bit of the poisonous smoke.
"You should sit down and drink this; rest. You must have inhaled a lot of the toxic fumes," Theodore said to Cassian, who looked quite pale at the moment.
