About a year and a half
Ivypool's parents are Whitewing and Birchfall. Whitewing is her mother and Birchfall is her father.
Dovewing told Ivypool about her unusual power because Ivypool was angry with Dovewing about the confusing secrets she had. I do not remember what book, I think it might be Omen of the Stars book 3.
No.
Yes she does.
Their warrior names are Ivypool and Dovewing.
Ivypool is not in the Power of Three prophecy because the prophecy specifically refers to Lionblaze, Jayfeather, and Hollyleaf as the three cats with the power to hold the fate of the Clans in their paws. Ivypool is their cousin and belongs to a different prophecy called the "Three" in the Omen of the Stars series.
Dovewing and Ivypool
No i don't think she will. Ivypool (as a warrior) found out that Dovewing (as a warrior) has the power of the stars in her paws. Jayfeather and Lionblaze ask Ivypool to spy on the Dark Forest cats for them when Dovewing tells them that Ivypool had been training in the Dark Forest. Ivypool seems disgusted with how the Dark Forest cats are training, so no, i believe she will stay loyal to ThunderClan and fight beside them when the Dark Forest attacks.
I know blossomfall, Ivypool, breezepelt, and tigerheart did.
Actually, I think Hawkfrost actually did have feelings for Ivypool. I mean, he always watched her and he was her mentor in the DF (Dark Forest) Look for hints in the Omen of the Stars series, cause I swear Hawkfrost loves Ivypool.
No, but Hollyleaf, Firestar, and Ferncloud died, and Spottedleaf died for the second time.
No she does not but bumblestripe use to have a crush on her but now he loves dovewing.
