When saying "this one" when referring to yourself, is it first or third person?

Question

I have been playing a RP forum game and I believe that one of the other players may be locked into first/third person every post he makes. Which one it is doesn't change it from a gameplay view but it got me intrigued to find out which one it was. Here are some examples of how he uses it

This one bears no grudge

This one can neither confirm nor deny this accusation

In each of these, the subject of this one is himself. On one side I feel like it is third person because it is how I could address him as a third person. But the fact that he is talking about himself makes it feel synonymous with the word I and has the same impression which I feel is indicative of first person.

Answer 1

It is grammatically third person singular, no matter whom it actually refers to. That’s why the verb there is bears not bear.

Even blatant self-referral can wind up being grammatically third-person:

Silly me has better things to do.

There is no question that these are all third-person uses, even if silly you thinks otherwise. :)

Answer 2

'I' (or 'me' in objective case) is the only first person word in English.
