Why is Chanelle the only housemate to call him 'Zach' instead of 'Ziggy'?!
Question:
Why is Chanelle the only housemate to call him 'Zach' instead of 'Ziggy'?
If anything's bunny-boilerish it's that. It's actually quite bizarre.
What's with having two names anyway? it's not like Ziggy is a nickname for Zach.
Is it some weird territorial behaviour?
Answers:
I think she doesn't like the name Ziggy and prefers his real name, also by calling him a different name it is more personal and like you say 'territorial' - most family members would call him Zach and his friends and the BB public would call him Ziggy.
