It made sense to get rid of Phoebe.  When she entered the villa, she wasn’t interested in any of the lads and never gave any of them a chance or spent any quality time getting to know them but she wrote all of the off even though there were a myriad of personalities and body types.  She clearly wanted to get to know Cassie when coming into the villa but why expect someone isn’t opening bisexual or a lesbian to all of a sudden be open to a lesbian relationship.  Although Phoebe claimed she’d never been in a relationship with a female before she mentioned in a previous episodes that she was coming out to her family she liked women.  This was probably not the show for her since production would have had to send in a lesbian woman who was willing to be in a relationship Phoebe.  And if that didn’t work out, then what?  Who else would Phoebe couple up with and who else would the newbie lady couple up with?  It doesn’t make sense in this format.
