Melanie Puckett

"You know, one time she tried to convince me I was adopted."

- Melanie talking about Sam's trickster history

Melanie Puckett is the identical twin sister of Sam. She and Sam were born on a city bus. Her only appearance was in iTwins. She was mentioned twice after this episode but never before, due to Sam's dislike towards her.

Personality
Melanie's personality is the complete opposite of Sam. She gets straight A's and goes to a fancy boarding school on a scholarship, which means she is often out of town. In iTwins she comes to Seattle to visit her family, much to Sam's distress. She is also a little more traditionally feminine than Sam and is known as the sweeter, nicer and more classy girl of the two. Since Melanie is the opposite of Sam, Sam admits that Melanie makes her sick.

Melanie is Pam Puckett's favorite daughter. In iSam's Mom she asks Sam "Why can't you be more like Melanie?" which extremely upsets Sam.

Role
In iTwins, Freddie believes that Sam is just trying to prove he's gullible when Melanie comes to visit. He wanted to prove that he wasn't gullible after being tricked by Carly and Sam that it was Clown Day at school. He even goes so far as to ask Melanie out, thinking that she was Sam, since Sam would not likely go on a date with him. During the date, Freddie continued to deny she was a twin and she tried to convince him by kissing him. This caused Freddie to run out in shock. At the end of the episode, Sam tells Freddie that Melanie is not real so he would stop bugging her about it. Shortly after Freddie leaves, Melanie comes up the elevator, proving her existence to the audience (but not to Freddie).

An obvious clue for that she couldn't possibly be Sam was when after Freddie pushed her shoulder, she exclaimed "Ow!". Sam never let on that Freddie could cause her physical pain. Another clue is that Melanie fits the "girly" stereotype, being soft and weak, while Sam is more tomboyish, having a tough and strong nature.

Freddie Benson
Melanie seemed to like Freddie as soon as she met him. She didn't blame him for thinking she was Sam, since she knows how much her sister likes to prank people, as Sam once tried to convince Melanie she was adopted. Over the course of the episode, she tried to convince Freddie that she wasn't Sam several times, even going so far as to kiss him during their date. He warned her not to kiss him again, as he and Sam had made a pact where they swore not to speak of the kiss (or actually kiss) again. When Freddie ran away from her, Melanie chased after him, and even so, she still finds Freddie adorable. (see Felanie)

In iThink They Kissed, Freddie states that the "other time" he kissed Sam might have been her twin sister, adding that he was "still fuzzy on the whole Melanie thing." This indicates that he had accepted that Melanie might be real, though he still wasn't sure.

Sam Puckett
Sam and Melanie are polar opposites, even though they are identical twins. Their mother Pam Puckett tends to compare the two, much to Sam's disdain. Melanie is the more responsible one of the two, but they do appear to be ok spending time together as seen in iTwins.

Sam apparently likes to play pranks on her sister; According to Melanie, Sam tried to convince her she was adopted at some point and in Sam's Rainy Day Checklist blog, she said she hid sardines in Melanie's room so her room would smell of rancid fish when she comes home for Christmas.

Carly Shay
Carly seems to be a good friend of Melanie.
