There's nothing to be confused about. I'm The Doctor. Last of the Time Lords. That's me. Anyone else is a fanatic. Or a possible case of potential paradox which we would really best avoid.
Thoughts on the portal. Let's see. It was a nice means of transport - no side-effects that I'm aware of, stable and secure. State-side? That's an unusual choice. All the places and times to go, and a portal brings us to Maine? Rubbish, that. Also, for the record because I potentially like you, it wasn't a wormhole. Have you seen a wormhole? Up close? Not a way you want to go. Doubtful you'd survive. Depending on transportation and the stabilization there in. This was entirely too... nice to put it simply.
Now, those thoughts aside, a quick transport to a place with gadgets and the like? Fantastic, for the time being, until I get bored.
