Hi, Greg. I'm really loving Phantoms so far.

I had a question about the Team's B-designations.

Obviously, the Zeta-Tubes and designations are a very integral part of the show. Prior to Season 1, Dick, Will, Kaldur, and Wally all knew and have fought beside each other.

I find it difficult to imagine they didn't use Zeta-Tubes during that time period, since even Roy knew how to use one (which would seem odd otherwise, considering his brief time as Speedy).

But the B-series was clearly created following the founding of the Team, considering Will's designation is B06, despite him/Roy becoming a hero before Kaldur and Wally.

Since none of them have A-designations, how did the four proteges utilize the tubes during that time, if at all?
