I figure after his first change Ienzo probably gets bounced around various Garou mentors for a while because there aren't many Bastets out and about and of those all have more important things to do than look after some stray. It's not like the wolves know what to do with him either though so eventually the local pack just dumps him on Bertie. Here, you're both inept. Make friends.

I mean he's got an obnoxious werecrow and a werecrocodile looking out for him but apparently werewolf relationships with both of the above are a bit strained.
