Lancelot Du Lac is many things. Friend, enemy. Hero, villain. Loyal, traitor. But above all else, Lancelot Du Lac is a Knight. Lancelot is the Knight. He is the greatest knight of the greatest brotherhood of knights ever to exist. The one that all knights past, present and future compare themselves too.

BANG.

A gunshot rings out seeking his disguised form. Beserker turns his disguised head to look and the source of the gunshot. His madness raveged mind evaluates the woman who attacked him

Female, magically enhanced. Skilled, but ultimately a minimal threat.

In most worlds that is the end of it. Maiya Hisau dies in furtherance of her masters ideals. But in some worlds… In some worlds Lancelot takes a second look.

Knows she has know chance. Still wishes to fight.

A glance at his true target settles the matter.

She is protecting her master.

As he charges he looks into her eyes he revaluates Maiya

No her [Queen].

He sees a glare that he's seen countless times before. And mind taken by madness or not, Lancelot recognizes her for what she is.

She fights for ideals not her own.

She is a [Knight]

It does not matter for what ideals Maiya Hisau fights for. It does not matter that she fights with ruthlessness and treachery surpassing any foe Lancelot faced during his life. Those are the ideals of her [King] Kirgitsue Emaya and she fights because she believes in him. To Lancelot that duty, that loyalty is what defines what a knight is far more than any skill at arms.

Her [King] gave her orders to protect his [Queen]

She is a [Knight]

She believes in him.

She is a [Knight]

Lancelot's mind flashes back to the first night of the war, the Saber he fought.

She is a [Knight]

She fights for her [King's] ideals

She fights with my [King]

Lancelot shakes his reigns and charges at Maiya, obedient to his master's commands.

She is a [Knight]

She fights with [The King of Knights]

Miya fires, seeking to cover her [Queen]. Her Emotionless face showing fear, not for herself, but for her charge. Lancelots maddened mind still whirls in confusion, barely comprehending the world around him.

She is a [Knight]

She fights for the [King of Knights]

She is a [Knight of the Round Table]

With a supreme act of will, Lancelot seizes control from Berserker briefly.

NEVER AGAIN!

He shifts his stance slightly, a killing blow changes. A strike to the head brings unconsciousness, rather than slow death. A blow to the legs ensures that she will not participate further in the war, fulfilling his master's commands.

I shall not kill my [King's] [Knights] ever again.

Lancelot Du Lac is a Knight of the Round table, and nothing, absolutely nothing, shall ever change that. As he leaves with Irisviel von Einzbern he has only one thought in his ravaged mind.

My [King]…

Behind him, and unconscious knight takes a shuddering breath. And thus, the world changes.

A/N:

This is a one shot currently, but I have a few ideas for a sequel set in the 5th grail war. Rin's attempts to act hostile and bossy to Kiritsugu's son might end up with a gun held to the back of her head. Also, a rematch with a certain fake priest might be in order. As for meeting Illya, well, expect fireworks.
