So the number following an exos name is how many mind wipes they've had. For example Cayde-6 has had six mind wipes. Generally a mind wipe is performed after an exo experiences something quite stressful or traumatizing that causes them to malfunction or something. Banshee's number is [b]44[/b]. Banshee has had 44 freaking mind wipes! What kind of far out crap must he have seen?
