While we don't know for sure whether Hollyleaf joins Starclan or not, there are three main theories on this topic. The first theory says that she does not join Starclan because of her actions just before she died. The second theory says that she will still join Starclan in spite of this. Another theory says that she is not dead at all, but is trapped beneath the tunnels.
(Actually, Hollyleaf didn't die. Well if she did die, everybody should know that she will go to Dark Forest.)It's unsure whether hollyleaf went to starclan or not. there has been no evidence that she is in the Dark Forest or Starclan.
Graystripe is not dead yet, when he dies he will join StarClan.
Yes, in the book The Forgotten Warrior (Omen of the Stars) she returns to ThunderClan after living underground and hunting on the other side of the hills. She returns after helping Ivypool and Dovewing out of the tunnels, and confesses to the clan that she killed Ashfur. She is welcomed into the clan, but rejected by some of her old clan mates for some time. But she also helps the clan train in fighting in tunnels. You can read the story of her in the tunnels in the newly released book, "Hollyleaf's Story"
No he does not, because he knows they are kin. Starclan told him but he was told not to tell anyone
Now he does, since he's in StarClan.
It is unsure where she would go. because she is alive, (confirmed by Erin hunter) but if she was to die she would most likely go to star clan because she did not kill in cold blood. she did it to help her brothers and clan.
Usually they get along very well, however once Yellowfang attacked Bluestar saying that she had betrayed the Clans, but even then her claws were sheathed, I think. yes they where, and i need to know this one hting DID HOLLYLEAF GO TO STARCLAN!?!? It is unknown if Hollyleaf did. The next series Omen of the stars will tell. Some starclan cats do get along, oh and yellowfang did have her claws unsheathered but she didnt hurt her.
oakheart came and brought her to starclan.
The Darkest Path.
No one knows yet, I personally think that the forgotten warrior is HollyLeaf and she is really alive trying to get forgiveness from her clan and especially, Starclan
It is not confirmed when, but it will happen in Omen of the Stars
In the warriors series, the cats that join Starclan are those who die and have followed the warrior code, and served their clan faithfully.
