Ideas/Inspiration needed for WIP dual companion mod.

[mutieblaster]

I'm currently quite a way into designing a pair of companions contained in a single mod.

I plan to have it fully voice acted, so I can implement a proper back-story and have plenty of dialogue and a few quests.

I have a rough back-story, which I'm trying to keep reasonably lore friendly. Part of my reason for posting here is to get some opinions on the story and whether it makes sense.

Rough timeline of back-story:

2198 - Enclave begin developing new Tech. Among early projects are their distinctive Advanced Power Armor, and FEV research. Intel shows existing FEV research in Mariposa Base and Vault 87, Enclave begin to search.

2222 - Group of 8 Enclave personnel leave Poseidon Oil Rig for Vault 88.

Vault 88 is part of the Vault Behavioral Projects, built to observe Vault 87 and remotely store it's research data as a backup, with facilities to further test any findings.

2225 - One of the team, a soldier who volunteered for the roll, begins FEV exposure.

2227 - FEV soldier sealed into armour.
2 of team killed in Deathclaw attack near entrance to vault.

2230 - Highest ranking member leaves on routine flight to nearby Vertibird refuelling outpost (remnants bunker), but never returns.

2235 - Reactor malfunction kills 2, injures 1, ghoulifies 1.
Injured exposed to FEV as only chance of surviving injuries.
Soldier now 10 years into long-term FEV treatment, withstands blast and immune to rads.

Up to present - Remaining team of 3.
FEV Soldier now a behemoth, Injured combat technician now a mutant, and pilot now a ghoul. Team ends communication with Enclave, fearing extermination. Enclave command get a readout detailing reactor explosion, team presumed dead.

Basically the mod consists of the pilot, and the technician who is now a super mutant. They are found in Vault 88, at the south end of the canyon.

The ghoul character is uniquely dressed in his enclave flight gear, and will have a quest to repair his Tesla armor. He also has a unique plasma pistol, and a further quest will give him a rifle. Both weapons and outfits can then be swapped on command. He can also give power armor training and use a stealthboy if you give him one.

The mutant character is equipped with a heavy incinerator and hopefully a unique melee weapon. He has a quest which on completion will allow him to call up and dismiss the behemoth held in vault 88, who was the third survivor. He can repair your weapons, and will cloak like a nightkin when you crouch.

There are just one or two areas where I'm stuck. I'm stuck for ideas for a good hiring quest, also my characters need names and personalities.

Any ideas in these areas, constructive criticism on the story, or other features to add would be hugely welcome.
