RedDwarf: Think hard and inventory check.
RedDwarf: ...appreciate the loyalty.
RedDwarf: We got this far splitting and convening, so we do that now.
RedDwarf: We need someone to raid the chapel, to get that disk.
SyndieCyborg: I've got a teleport module, and enough energy to use it twice! Once you have the disk, tape it to me and I'll get it to the vault.
RedDwarf: Good.
RedDwarf: We need someone to get the infiltrator shuttle in position and ready. Maybe bring a teleport beacon there.
RedDwarf: And we need someone at the vault to snatch the disk and set our little gift off.
This plan's going to be difficult. Your unspoken secret objective is now in play. You must make sure that, no matter what plan gets made, you find a way to be alone in that vault for long enough to retrieve your objective. You can't afford to have the others know. They're your trustworthy team, and that's why you can't ever put them at risk that great.
