You are an former imperial trooper, but decided to join the rebels after the empire has fallen. Some don't trust you, even though Ackbar told them to accept you. You are still wearing your imperial helmet. Meet the other rebels:

Jack:"I'm excited! They could tell us so much about the empire and their plans!"

Jira:"Is it a good idea to have an stormtrooper here though? They would be dead if they would betray us, but still...I'm unsure."

Onnes:"They've changed. I'm sure."

Salarac:"Maybe."
