Oh I will admit I'm not a fan of Major Sam Carter. The writers of StarGate SG-1 had a chance to create a strong female character but they failed and made her into a plot hole fixer. Need a way to escape a death trap, Carter will do it. Need something fixed… Carter will do it. Need someone to kick but and take name… go see Teal'c.

Xander is arrested for the murder of Major Sam Carter. The reason being the murder is she was a demon.

Carter's breed of demon likes to collect men mostly as their personal harem. They find a male they like and they decide to keep them close by. Any other female who gets close to their males are either drive off or killed.

For example shortly after meeting Daniel Jackson his wife, Sha're is kidnapped by the Gou'ald and is eventual killed. Teal'c loses the two women in this life that he came to love. She even influence Colonel O'Neill, driving away any other women so he was centered more on her.

So when Xander stumble across her as she tried to remove another threat to her harem, he killed her. Now he has to convince the military that he was the good guy

Xander and Faith forming a strong bond of friendship as one emotional-mental-physical-sexual abuse victim recognizing another when faith comes to sunnydale earlier - leads to them getting some mutual unconditional platonic love, affection, honesty, respect, comfort, acceptance and training leading them to being happy and healing.

Together they = Patrol sunnydale poorer areas & the underground, = earn top scores on their GED, = improve their Self Defence & supernatural knowledge, = make contacts through the kitty poker circuit, = loot caches, = pickpocket vampires, = hustle pool/darts & cards, = learn some necessary life skills, = undergoes a in-depth cleansing ritual, = get gifted in heavily warded Lapis/Koa rings from a truly peaceful race, = live/squat together, = proactively take out several threats before they become active threats in inventive ways such as Judge/Dru/Rack/Doc/Spike/Sisterhood/Belthazar depending on when Faith arrives,

Rings: warded against being taken off, unwilling teleportation, physical & spiritual possessions, harmful/malicious & shoddy magicks, tracking, impersonation,  mental & emotional compulsion/influence & tampering, unwilling magical & psionic bonds...

Also leads to Xander revealing some secrets such as = squatting/camping at Jesse abandoned house, = living out of a dufflebag, = his parents & willow illegally changing his name/birthday/various records to either get him out of the house sooner/later or mold him to be dependent.., = having legal & accurate records which show his true talents/aptitudes/health.. as well as a healthy bank account under his birth name outside of town without anybody in sunnydale knowledge, = being a single parent to a son due to sexual assault, = taking online classes..

How would things possitively change for Xander with someone at his side like a true sister who saw & accepted all of him as he is?
