#i haven't read the A1 manga either

[talos-to-listens]

Going through the archives of all of Reserve Team A1's Alters there's a few points to note.

Kroos accidentally fire on a teammate, and that teammate sustained a scar. We can see that Fang Alter has a noticeable scar on her stomach. This points to Fang Alter being the teammate she accidentally shot. Her archives also implies she sees the scar often, which also lends credence that whoever she shot survived with a scar.

Lava appears to have nothing that we can read, because records about "a certain event" are redacted. But there is a line, "the children who grew up in such difficulties and hardships would know how to cherish their own lives after they come to understand loss." This implies that someone close to them either passed away, or left Rhodes Island after the redacted incident.

Hibiscus' archives has an even more somber line. "If only everyone were still here for it." This again seems to imply that someone has either passed or is no longer with Rhodes Island.

Both Sarkaz sisters have also, throughout the years, have acquired similar habits of self sacrifice. Lava's archives note that with every major incident her resolve and determination grows, but her mental health deteriorates. Similarly, Hibiscus frequently lacks to mention potential conflicts or incidents that occurs on her missions on her official mission reports.

Finally Beagle. She has no Alter, but instead she has a Bloodline of Combat skin. That states it's her appearance after being promoted to an elite operator, the gear she wore on the Great Bolivian March when serving as the rearguard. It also includes the line "This is her final test".

That said though, Beagle's Dreadnaught skin is one of the earliest BoC skins, which may be have been designed before HG had truly figured out what, if anything, they wanted to do with A1. Also "Dreadnaught" can be translated to fear nothing, which is pretty fitting for a defender operator.

Taking everything into consideration, we must come to the conclusion that something happened to Beagle during the redacted incident. Either she died, or was injured in such a way that she no longer serves as an operator for Rhodes Island.

Why did I see the need to type this out? Because part of me is going crazy waiting for a Beagle Alter to confirm she survived, so I gotta mentally prepare myself for the possibility that my baby Beagle ... didn't.
