Trying to give every player a target (another player)?

I am trying to give everyone a target and a person targeting them, so person a might be targeting person b but is being targeted by person c. I have tried this, I do not believe it will work, but I can't test it in studio, because it requires multiple people. I have a problem because what if person a's target is person b and person b's target is person a and there are only 3 people in the server, person C will have no one to target. I can't make it so you can't target your hunter otherwise the final two won't be able to hurt each other. This is my script:

--[[Values]]
--[[Tables]]
Players = game.Players:GetChildren() -- Table of players

--[[Checking alive players]]
if player.TeamColor ~= "Grey" then

Colours = {
    BrickColor.new("Sand red"),
    BrickColor.new("Sand blue"),
    BrickColor.new("Sand green"),
    BrickColor.new("New yeller"),
    BrickColor.new("Br. yellowish orange"),
    BrickColor.new("Lavender"),
    BrickColor.new("Dusty Rose"),
    BrickColor.new("Deep blue")
}

--[[Colouring]]
function Assign()
    for a = 1, Players do
        a.Character.Parent.Torso.BrickColor = Colours[a]
    end
end

--[[Current players (The players still alive)]]
function Alive()
    Current = Players
    for i in Current do
        if i.TeamColor ~= "Grey" then
            Current.remove(i)-- No idea how to use this
        end
    end
    if #Current == 1 then
        Win()
    elseif #Current == 0 then
        Target() -- Start again
    end
end

--[[Selecting Hunters/Targets]]
function Select()
    b = Players[math.random(1, Current)] -- Random player 
    if a ~= b and a. Target == nil then
        a.Target.Value = b.Name
        b.Hunter.Value = a.Name
        print (a.."/'s target is:"..b)
        print (b.."\'s hunter is:"..a)
    elseif a == b then
        Select()
    end
end

--[[Win]]
function Win()
    print (Current[1].." won!")
    Target()
end

--[[Target, Hunter]]
function Target()
    Assign()
    Alive()
    for a = 1, Current do
        Select()
    end
end

wait(5)
Target()
