I remember asking my friend, "Whose your favorite character in 'The Host'?" while I was still in the beginning of it, and she said, "Ian." And I read further, wondering who the heck Ian was, and then he tried to attack Wanderer. I'm all, WTF? Why do you like him.
Then after the scene with Kyle's attempted murder and he kissed her on the head! OMG! I was all, "He looooves her!" and as the story progressed, I came to love Ian and throw away the whole Jared thing. He's just so sweet and loves her for who she is and not the body she's in. At the end when he said, "I held you in my hands Wanderer, and you were beautiful," I literally melted. How wonderful was that????
I think he started loving her when he had to help Jeb look after her. During that, he started to consider her a friend, and then later he was crushing on her. Also after she discovered the murdered souls and he was comforting her. AWWW!!
