Aw - cant see the piccie on me work poota for some reason, but glad to hear that the vet visit went relatively uneventfully and hoping that he's improving all round
Seems like he's quite protective of his food, although to be honest, I tend to give ours their food and leave them in peace to eat it, as many cats dont like to be fussed whilst they're eating. Thinking about it, I guess I don't much either
If the aggression towards Bebe persists or gets worse, you could try taking them back to eating either side of a closed door to see if that eases the situation, then gradually leaving the door a little ajar - maybe give it a week or so to see how it goes. If that doesnt work, then either feed them separately, or put them at either side of the room.
Am pleased bebe seems to be eating more again.
Aside from his tummy trouble (which I hope can be sorted very soon) and the slightly anti-social food situation, they do seem to be getting on very well.
