And again, the loss of the Matrix only really comes into play if Prime dies. Just the news of loosing it isn't an indication of "enormous value" for the Matrix itself, rather, they're more concerned what would happen if Prime died while they didn't have it to pass to another potential Autobot leader. But as long as they've got Optimus alive and a shred of hope for his recovery....
Uh, you yourself have said that knowing they lost the Matrix would be a blow for the Autobots. At that point, morale is pretty much all they have, and it is appallingly low, as evidenced by the sniping the 'bots are doing. Prowl, Jazz and Kup clearly are operating under the assumption that the perception of having/not having the Matrix is important, hence its value. (It is *useful* politically, and the truth would be very costly for the Autobots in terms of morale.)
"Not that out of order"? The Earth bound Autobots have no idea what has been going on with Cybertron up to that point, no idea what they were getting into. Mirage blindly and selfishly getting his comrades captured is extremely out of order. They don't know if Ultra Magnus can be trusted, Autobot or not, especially given the hostile actions being taken toward them.
On the other hand, Shockwave correctly assesses that the Autobots are likely going to be trouble-makers. Shockwave was sincere in wanting to end the war, if only so everybody could fight Unicron. (He was pretty worried about that.) And, hey, would it really be that bad living under Shockwave? Really, so what if he is a Decepticon. The trains ran on time and there were energon spas. Look at Skywarp and Thundercracker. They had the right idea. Enjoy the peace while it lasts, and (when the time comes) pick a side.
Can you blame Mirage for wanting a piece of that pie, rather than going along to get along with a bunch of guys who would just perpetuate the war Mirage wanted no part of the in the first place?
It is not like there were not Autobots working with/for Shockwave.
As for the Matrix.....
But, there are character actions and dialogue, clearly on the page, that illustrate the Matrix as important to both factions. It is not a question of assumingthe reader recognizes the Matrix is important. McCarthy has the characters talking and acting like it is. What level of explication is needed here?
Is the universe exploding again? No. That only happens on alternate Thursdays when Furman is in town. But, the Autobots are in pretty dire straights, and keeping up some kind of morale is important.
The Matrix also holds some kind of value for the Decepticons.
I can see Megatron taking the Matrix just as a way to stick it to the Autobots, even if he only plans to use it as a paper-weight. At the very least, taking that Matrix gives one bragging rights. And, if there are other uses to the Matrix, Megatron gets access to those as well. Remember, he did rummage around for the Matrix in "Devastation". And, "Origins" was early enough in his career that the idea of taking the Matrix, let along announcing it to the world, may not have occured to him when he was still fighting for "workers rights".
At that point, the Decepticons were just a rag-tag bunch of thugs and malcontents, not an army. They were an insurrection, (dangerous yes), but not an army. Bandits and such can be dangerous. They can fight armies and win. (History provides ample precedent for this.) But, conflict with them is not necessarily a war.
I'd rather like to see an interaction between Mirage, Smokescreen, and Hubcap, as some of the less trustworthy Autobots.
I suppose there could be some irony there. The 3 guys you mention are all different enough that they would likely not see the similarities between each other.
(I am using "favorability in the electoral sense.)
Mirage is seen as not being loyal enough to the cause. Most Autobots wth an opinion of him likely see him as low on favorabiiity. Mirage cannot run for political office after the war. Heck, he probably needs to make sure there are not certain parties behind him when he stands near a ledge.
Smokescreen on the other hand is generally seen favorably by his comrades. Yes, you and I know he is a bit sleezy. Yes, some Autobots know he is a bit sleezy. But, many of them would likely look at him and say, "Well, that is our Smokescreen, always up to something." Even the guys who know Smokescreen narcs to the boss about what they are saying in the trenches know that Smokey is loyal. He could totally run for office and win.
Hubcap is just a twerp. He is either seen as a lazy hack or a confidence man. Nobody is likely to trush him with much. And, they are unlikely to have lunch with him as he is likely to bum money off them for the check. But, they would likely talk with him while on break, which they would not do with Mirage. And, some guys might cast a vote for Hubcap, if they thought he would be in their pocket. Nobody would care if somebody dropped Hubcap down a pit, but nobody would likely bother to do so themselves, unless he owed them money.
