Oculon - 2819 - Defiance: The Hyperion Arrived in Heleus in 2819.

It sounds like the geth says this is normandy, but if you clear the noice he says checking or hacking, with the latter being more possible. As for the rest it's hard to make out what he says.

Maybe the geth hacked the terminal and liara said, i can see it. She might refer to the ship or the relay. If she refers to the relay then there's an explanation for the word defiance. There's a secret group named DAGGER Ltd on last years video. Maybe that group had enough money to build a relay, in a far away system named Satherium. Maybe there's some ex Cerberus members and thus Cerberus exists again and is being rebuild under the name DAGGER. They can have someone funding that group. It could the benefactor or someone new. Now there's only one mass relay on the video and that relay leads to Andromeda. Now what and why they want to go there in secret is a mystery. Maybe it might connect with something that has to do with the benefactor? Maybe that human- quarian captain might know about the quarian ark? Is he the benefactor or he's with that group that build the relay. Also i think in the new teaser that person is on that new system. Probably to investigate about that secret group and that perfectly aligns with liara and the geth talking about defiance. That group had defied the council for whatever reason and they work to build a secret relay to connect with andromeda for something we don't know yet. It could also lead to another place but for now I'm gonna say andromeda since it's more prominent in the teasers.

"Human defiance

That's a key word that continues on that teaser. The previous teaser continues with the new one. So that group which is led by humans have defied the council for reasons that are still unknown, maybe it has to do something with that distress signal? The distress signal could be sent sometime after the main events of Andromeda, although why send a distress signal in the first place it's not like someone is going to help them anyways. Maybe it is the communication thing since on Andromeda they tried to communicate with the mw but couldn't get a response from them. Also that woman who said on the very first teaser "is anyone receiving this? We've lost contact". And the year it was send is the same as when andromeda's events take place or some years later.

Now there's the key word human that is very prominent in the new one. The previous key word [human defiance was about last year's video as i explained above with the group. so, let's go back to the human word. Gamble yesterday called that character a person, so that means the one we're looking at is probably a human. So that human is gonna investigate whatever's going on with that secret group by liara's orders. They're an n7 as we've seen and they work individually, away from the council's orders or maybe they do report but they keep things a secret i guess. If paragon/renegade options are back as it's been teased on the new art then that's possible. They can be completely honest with the council, be neutral or mean (lie) if the council asks for specific things. A more diplomatic/agent type of character that works under others people's orders but has their own motives.

2819

Now the year here is about the events that are gonna place on the mw, along with andromeda's events or it's some years after andromeda's events.

At first i thought that that n7 character is liara since gamble teased that she's gonna have a third role, and liara taking that piece off from the ice despite meaning that the franchise is back, it could also mean that liara is an n7 now. Last year's video also had red and white stripes,but weren't very visible. This along with the above makes sense but since gamble called that character a person it changes things, or he wants to confuse us. It could be anyone so we'll see. He also said not everything is as it seems after the teasers maybe referring to the theories or something else.

Edit: gotta say though the boots are the same as liara's from the 2020 teaser.

Shepard and their crew really have no reason to have deep interest to jump galaxies to same Andromeda Initiative, assuming convoluted reasoning they are still around. They are not but for Liara, with potentially Grunt and EDI. Maybe Wrex, Samara and Javik( Prothean max age is unknown).

Liara may be the only one personally interested, because she did helped them in later stage of Andromeda Initiative Arks development.

Regardless, when Liara calls humanity defiant, she says it in a very negative tone. As in she is sick of their yet another bullshit stunt. Potentially she doesn't want for whatever Earth government there is in MEA timeline to get in contact with Nexus, but the N7 agent in teaser trailer managed to break into Shadow Broker communications and get access to do just that.

Why would Liara do that? How bad is Earth government 6 centuries later? What do they want with Andromeda?
Speculations for everyone!
