How do you get link?

It is all about how you think about Zelda. If you think that "young Link" (age 8) is the "real link" the he is 8 but is you thing "Big Link" (age 14) is the "real Link" then he is 14.

well yes and no. if you mene smaller yes. in age no. they are the same age. but are the same

At the beginning you begin in his house if you have the flute use it and go to warp number 4 to go there.

yes and no dark link represents the evil side to normal link meaning that everyone has a dark side or dark side

Yes, he is the same person but the only difference is that Link is in the dark version but your answer is yes. Dark Link is the same as normal link the only change is the collar.
