[spoilers] Lucas. Just Lucas.

Dumb Question Time - Why does everyone assume that Lucas North is an assumed identity and John (Thornton? Porter? Standring? Mulligan? Actually, my money's on Gisborne.) is the reality? I know that RA said before the series started that Lucas wasn't who he/we thought. I know Vaughn asks what's like to be Lucas North. But I assumed that RA was talking about Lucas's character rather than identity, and that Vaughn's question was meant rattle Lucas with the knowledge that Vaughn knows his real name and knows that Lucas was on an operation when they knew each other in Africa. It makes more sense to me that Lucas was working for MI-5 and John was his legend than Lucas faked his identity from the service and Harry when he joined. Have I missed something?
