Whether you like him or not, or think he's genuine or not, the Bambino was playing a blinder in BB strategy terms. Haven't seen the reasons why today, but he seems to have upset Ant & Dec and their double D sidekick, which seems a big error and makes me believe he wasn't so much playing a calculated game as lucky till now.
Before today (if he has upset the above) seems to me he'd done everything right in strategic terms to guarantee a final three place and never be up for a nominated eviction. To guarantee that seems to me you need never to align yourself with one group, to be the 'bestest' friend of noone but to be reasonably ok by most people, while at the same time not being so invisible as to be a non-entity.
Roberto had arguments enough to assure he couldn't be labelled a fence-sitter and invisible man trying to sneak his way through. His arguments had some rationale, rather than being plain bitchiness, and events (the running out of food, for example) had a high chance of convincing some he had argued with (Science, for example) that he might have been right all along. So he jumped that hurdle.
He had managed to avoid aligning himself solely with either of the defined house groupings; he belonged to neither. But neither hated him. His only risk of nominations, as the two main groups would get down to the business of trying to eliminate each other, were from Kermit the Diva and possibly his sidekick Miss Makosi. Those two weren't strong enough to get him nominated, and one of them would have gone before him, I think. The 'lads' thought he was an ok bloke, lesley fancies him; he kissed The Craig (toads don't forget such things

), he and Derek get along, Science had already got over his kneejerk antipathy to him, Vanessa and Sam had bigger fish to fry than him in their nominations and both would have been gone before they ever got chance to get to him.
So the Bambino had it wrapped up. Haven't seen it, but by apparently upsetting the 'getalong gang' today, he may have messed that all up.
