Of all the places to go, why did Vert end up at the Silencerz Base? Maybe it was because their hologram of the Wheel of Power was the only one operating at the time. If I were Vert I would've been expecting to return to the Accelerons or at least back at the beginning of the Ultimate Race.

I was surprised that the Portal worked anyway. Maybe it had something to do with the AcceleChargers he was carrying

Also, when Sparky used the EDR, why did he not reappear back at the Acceledrome (or what was left of it)? Lucky for him that he returned to Highway 35 instead.
