The nickname “Two Tubes” isn’t just a catchy callsign — it directly refers to the two permanent breathing tubes connected to Edrio’s vest and backpack. These tubes are necessary because the atmospheres of some worlds where Saw Gerrera operated (such as Jedha) were toxic or heavily polluted, even for the Tognath species.
