It is unclear: was Migau or Jerome mentioned in the story? How about: “Migau was surprised to see his brother on the cover, and even more surprised to see Jerome’s name mentioned in the story.”

Confusing sequence of information: the cover… the story… the Royal Science Society (now I’m thinking it’s the Society’s publication we are looking at)… But [the] gossip rag (Huh?) Could you work in the “gossip rag” in the first sentence? Then go on to talk about Jerome and the Society.

And too may proper names! It’s enough to say that students at the Royal Science Society are groomed for OR given a boost into important positions in politics and science (or whatever). If you can shorten it up, then maybe give us a taste of the story? Was the photo compromising? Certainly if he opened it and saw Jerome’s name then he saw it in context, and I’m curious! Don’t withhold your POV character’s knowledge in an attempt to create suspense; it’s frustrating. Even if all he saw was one sentence and slammed it shut.

The fragment “This Jerome had to see” made me think for a moment that we are in Jerome’s Point of View (POV). Wouldn’t the person buying the rag be thinking that HE had to see it? (Also that sentence is repetitive.) How about: “This he had to see—and, of course, Jerome and their mother would [need] to read it too.” Or take it a step further: “This he had to see—and he couldn’t wait to wave it under Jerome’s nose! What would their mother say?” Something about the expected/hoped for reactions?

You could replace “Arrondise bell” with "church bell" or “bell tower”. We can get the name later, if it matters.
