Coldstep's plot

Coldkit is a regular, stubborn kit
Stormwing is a little too strict with him(Cold's own fault >.>)
Stormwing is killed saving Coldkit, right in front of his eyes
Coldkit becomes a bully to the other kits until he's apprenticed
Until then, Raincloud and Creamstripe kind of mother him. Creamstripe being the strict side to teach him right and wrong, while Raincloud tried to love him :3
Coldkit became Coldpaw(He never actually liked Cream and Rainy acting motherly to him ._.)
Coldpaw's mentor was Raincloud, who deals with him quite well, despite his rude attitude
Coldpaw joins the Dark Forest and kicks Happy's butt *shot*
Raincloud has a stomach ache, so Creamstripe takes him out for hunting
Coldpaw basically almost tears Creamstripe's arm off...and attempts to murder her out of cold blood
Singethorn appears, knocking Coldpaw away from Creamstripe and giving Creamstripe enough strength to drag herself to camp, while Coldpaw makes a scene in camp, lying about how they were attacked by a strange orange rogue she-cat, and he tried to save Creamstripe but failed
Creamstripe heals, but ends up moving to the elders' den because of the horrid shoulder wound Coldpaw gave her
Coldpaw is extra nice to Creamstripe, as if trying to repay her for "Not being able to save her from the rogue", therefor making his story more believable
Creamstripe is forced to keep quiet about what really happen, as Coldpaw threatens to kill her one day if she says anything

(I don't know what will happen during the rest of the time he's an apprentice yet...to be edited)

(When he's a warrior)Coldstep becomes a warrior
Eventually, after all this time, Lilystem is sent a message from starclan about how Coldstep had put Creamstripe in the elders' den, not a rogue
Coldstep some how finds out she knows, and on the day she plans to tell the clan what really happened, Coldstep murders her before she can(THIS IS AFTER DARK BECOMES A FULL MEDI CAT)
Eventually, Coldstep gets an apprentice and tortures him/her during training. Attempts to force join into Dark Forest(Lilystem's next life MIGHT be his apprentice...not sure)

Time skip....(not sure what will happen while he has the apprentice)

Coldstep completes training his apprentice and he/she becomes a warrior
Coldstep murders Raincloud, so he can take over as deputy, as everyone at this point thinks of him as a good, strong, loyal clan cat(except for Creamstripe XD. Bramblestar said he can eventually become deputy, but not leader)
Coldstep EVENTUALLY becomes deputy
Coldstep is really strict and a little mean when he does his duties, like interrupting Bramblestar during his orders, making his own decisions, or being very harsh when a clanmate disobeys his orders
After a while of this, Creamstripe is told by Singethorn and Maypaw a warning that Coldstep plots to take over Skyclan by killing Bramblestar. They also mention that Coldstep was the one to kill Lilystem and Raincloud! So she tells the leader once she hears, along with all the rest of the truth behind Coldstep killing Raincloud, Lilystem, and almost herself. Coldstep is exiled
Coldstep continues his life as a rogue and Dark Forest warrior

...The rest hasn't been decided yet :3 (To be edited)
