Could my nephew be gifted?

Maybe it is just bias, but I have noticed a few things about my nephew. He has a large vocabulary and is stringing words together, which is a normal level for a 2 year old, but a few incidences really surprise me. I was wondering how much a child should be able to ociate/ remember at that age. For example, he says go away, but he only ever uses it in context - when he is cranky, and really does want you to go away. The thing that really blew me away, was today when we were shopping he wanted to look at a table so I picked him up. He pointed at a Ford hat and said 'Shaun!' which is my brother's name - it shocked the hell out of me, since my brother is a mad ford fan and has a Ford flag in his room. I was so shocked that a) Zane recognised the symbol, and b) that he remembered that it was ociated with Shaun. Just to be sure it wasn't the colour he picked up on, I showed him a number of blue things today, none of which he said Shaun to, but later walking past the stall, he said it again when he saw the hat. I don't spend anywhere near enough time with him to make any more observations, since they live away, but maybe there is some other signs I might look out for if he is gifted? Thanks!
