Looking at them %'s I think they strategically announce the B2

I was under the impression it was always the actual B2 but Day 13 they said Crissy (7th out of 11) over Lorraine and on Day 18 they said Mark (3rd out of 6) over Willie... why just these?

Lorraine was booted out the next day when maybe being announced B2 again would have boosted her votes and she would have survived at least 1 more day. Whilst Crissy catapulted to 4th most votes.. maybe they saw more entertainment value in her? Meanwhile as 3rd was Mark's lowest position I reckon they announced him B2 to encourage voting... which it did to 1st place the next day. They clearly wanted him in the final, being the central contestant (focus on Antony friendship, Dougie friendship, Emily potential relationship, his different perceived attitude) and they probably didnt wanna risk him possibly plummeting to last in the next votes.
