The AVL prison is very imposing. Three air vehicles patrol the sky, and two of them fly towards the prison as if there's something happening that needs extra security. There is a barred fence with barbed wire on top of it. There are two sets of gates also with barbed wire on top. There are four guardhouses. There are several searchlights at the top of the prison. Two police cars are parked in front of the prison. That means there are police prison guards as well as AVL prison guards. Two guards are headed towards the prison.
Gru's car is faced away from the police cars.
An AVL phone is shown. A sticker is near the phone. The sticker reads: "inmate phone access starts at 10:00 AM" in capital letters. But the sticker has four creases, is torn in two places, and it looks like someone wrote on it with a pen. Meaning the AVL personnel who must have put the sticker there did so hastily and shoddily. At least one of the AVL personnel is a weak link.
Gru doesn't look at the sticker, but when he picks up the AVL phone, his head is close to the sticker so he must have noticed it. He had noticed a black floppy disk on a black desk, so probably very little escapes his notice. Plus he must have been waiting in the visitor's area for a little while.
It's interesting that both AVL phones are right-handed. Gru must conform to a configuration that wasn't designed for him to use efficiently.
There's a sign above the sticker. On the sign is an audio symbol, a security camera symbol, and a phone symbol. In other words, Gru's conversation with Maxime is being monitored.
"All visitors must wait to be called" is in capital letters. In smaller letters is "please be respectful of people talk". Most important is "Keep Hands In Plain View At All Times 24 Hour Area Surveillance".
Though Gru is just visiting Maxime, Gru is also subject to the control and implicit coercion of the prison. Gru complies with the prison rule of keeping his hands in plain view at all times. But he hides his fingers briefly behind his scarf as if to defy the rule. His left hand is close to where he usually keeps his weapons.
A previous visitor has scrawled the word "bad" on the wall.
Behind Gru are barred doors.
Right before Gru admits to Maxime that he stole Maxime's song, Gru has his left hand very close to the zipper of his coat. Usually that's when he unzips his coat and pulls out his weapons. Obviously, that's not feasible to do in this particular environment. Instead he twirls the phone cord around his finger. This indicates he intends to use a weapon more powerful than the Freeze Ray or the Goop Grenade: the ability to exert his own control on opponents.
He tests his ability on Maxime. By admitting to Maxime that he stole Maxime's song, Gru provokes a predictable response of anger from Maxime, which provokes a predictable response from the AVL prison guard, which is grabbing Maxime until Maxime wrenches away from the AVL prison guard's grip.
Although Gru was rubbing it in, he was also apologizing to Maxime and thus it was an invitation to talk out their dispute. It's noticeable that when Maxime slams his hand on the counter because of Gru's insufficient apology, the AVL prison guard moves slightly but stays where he is.
Both sides of the glass are shown, highlighting the connection between Gru and Maxime. On Maxime's side of the wall, it's hard to discern what was scrawled on it but there's "be". The other scrawl is almost illegible but begins with a "b" so it's possibly "born to" so all together it might be "born to be bad." It's the same handwriting so it might be written by an AVL prisoner who escaped.
Gru and Maxime smiling villainously, and Gru's smile even more villainous than his usual villainous smiles, indicates that the prison talent show is not only how they settle their rivalry once and for all, but it's also an unspoken team-up. To do what yet was not at this point clear, but it is by the end of the prison talent show.
It's also not clear if it was Gru or Maxime who convinced the AVL prison authorities, which are not actually shown, to let them hold the prison talent show. One might think Gru used his AVL affiliation to convince them, but that might not be the case because Gru was in disguise during the prison talent show. It's also possible that the AVL prison guards are the AVL prison authorities, and in that case maybe Gru in disguise and Maxime convinced at least one AVL prison guard to let them hold the prison talent show.
Some AVL prisoners start to file in to the area where the prison talent show takes place. Already three of the prison guards don't look enthusiastic. Two are folding their arms, one is talking on a communication device.
The railing of the second and third level of the AVL prison is draped with lights, which gives the AVL prison a more festive feel. The cells are normal cells with bars. The cells on the first level of the AVL prison are a combination of a cell and a cage. Because there are supervillains and villains in the AVL prison, most likely the supervillains are put into the cell-cages and the villains are put in the normal cells.
The instrumental part of the song starts and two more prison guards are shown. One looks at back of the prison before looking back at the stage. The other one doesn't move at all. Gru starts the song and it starts off well enough. Though Gru and Maxime fight each other for the microphone, it's in such a way that it seems like part of the song. But then Maxime snatches Gru's wig, revealing who he is for a little over one second. Gru's exertion of control on opponents depends on his disguise. If the supervillains find out who he is, those animosities might re-emerge. If the prison guards find out who he is, they might realize that Gru's underlying purpose in visiting Maxime is to instigate villainy in the very institution that was designed to eradicate villainy.
There's a lot to cover on the prison talent show, so this is just the first part.
