He is a cold soul who loves nothing more than the sight of the fallens (zombies) blood trickling down the roads. however when he is with the living he has a pleasant aura around him. as he was an electrician back in the day of the living he has a wierd sense of humour sick or otherwise.
Peter has: a pair of wire cutters.
a knife.
toolbox full of electricians kit.
electricians van.
keys to the van.
a python revolver.
and finally the mighty katana (which he stole from a dead body he found).
peter was on a buisness trip in america due to how he is british. he didn't if know anything had happened to his family but the infection was spreading throughout the globe at an alarming rate and he was sure that soon enough his family would be in the casualty list for world war z. he looted an abandoned military base with a few other "stranded". in this base he got the python and katana.
