No. He is dead. She is alive. He was (and still is) a tyrant trying to take over the forest, and she is just following him.
Spoiler :) She was because she thought it would help her become a better warrior but ever since Dovewing Jayfeather and Lionblaze talked to her and told her that they're bad and made Ivypool a spy she only does it because of spy missions.
He tricks her by telling her no one cares about her, that she isn't special like her sister, and that she doesn't need Thunderclan to be great.
She isn't told, but she over hears Tigerheart and Tigerstar talking. It reviles that Tigerstar had been lying to her. He was not helping thunderclan.
Yes and no.
Ivypaw is not interested in anybody yet. She used to be in a one-sided love with Tigerheart (from ShadowClan) but he loved Dovepaw. However, Dovepaw believes that Tigerheart does not love her so in a way, they broke up. Ivypaw will probably be interested in someone after she gets her warrior name which is in Signs of the Moon.
Theres a big battle between shadowclan and thunderclan(which Ivypaw suggested). Firestar dies and Russetfur is killed. Also, Tigerstar and Hawkfrost meet Ivypaw in her dreams, teaching her new moves. Tigerstar was the one who told Ivypaw to convince Firestar to start the battle. Theres other stuff but you need to read for yourself.
Not really, when HawkFrost sliced his belly open and then when IvyPaw saw that white cat with a scar on his stomache that was SnowTuft. Improvement: It was really Shreadtail who sliced Snowtuft's belly open.
it is quite possible because ivypaw was playing and joking around with him when they were collecting moss and blossomfall also seems to like him because shes been seen flirting with him and getting mad at ivypaw when they were hunting
No, as of Fading Echoes. They are already kin, so this will probably not happen.
No there never was a romantic relationship between Hawkfrost and Leafpool.
Dovepaw is the chosen one not ivypaw. ( I thought ivypaw was one of the thrre)
I dont know. She is really upset about how her sister is getting all the attention and is being a real pussy cat! Inside she is a good person, she just needs to be more relaxed and work out her problems. In books later on, Ivypaw is visited by hawkfrost, but she doesn't know he is evil. Hawkfrost tricks her into doing something horrible-- something you will have to find out-- but anyways he tricks her, and this causes a very horrible death.
