Star Munchkin Transporter Twin - Do One-Shots Count?

[RL]

Part of the text of the Star Munchkin 2 Transporter Twin card: "Total up the bonuses of all Items that you are using. The Transporter Twin has the same bonus."

If you use a one-shot, does the twin get that bonus as well?

Hmmmmmm. . . That's tough. I mean, should we only count one-shots that the main combatant uses, since the Transporter Twin is a duplicate of him? Or, should we say every one-shot gets duplicated? I know I just asked questions like I'm asking for an opinion, but in reality, I think I'm just going to say, "No." One-shots are to a "side," and we're now applying it that way exclusively since SJ has seemingly forgotten all the stuff he told me many years ago and now we can rule that one-shots don't get duplicated by something like Mate or Mommy. . .

1. What about Foof Gun if I don't use it?
2. What about Items with a variable bonus? (Primal Chaos)
3. What if I lose my permanent item or somehow start using a new permanent item during the fight?
