Will they replace Aaron
 

Or just keep the #4in newbies to keep the eviction numbers down ie no need for double eviction later

They already have

Channel 5 are making it up as they go along, so they don't need to replace Aaron.

C4 used to replace housemates because they had the entire series planned out - if they were down on a housemate, it would mean that they couldn't do that double eviction they were planning to do, or there would be one less housemate in the final, so they filled the spot so they could do what they planned.

C5 has never replaced walkers/ejectees so I doubt it.

Mark was replaced me Gemma

That week 5 housemates left and 4 entered add that to the fact one would have been evicted anyway there is no housemates down

Don't remind me about Mark, he was my fav even more than AAaron, so when they replaced him with Gemma for the Fay SL I was rather irkedpi$$ed off.

Really hope they bring in a girl, with the twins gone too the house lacks females.

No... The plan was for numbers to remain unchanged that week as four would have left and four would have entered. Aaron's ejection changed that so that five left that week and only four entered.

They ARE one down.
