[b][i]Obviously with somebody else playing Xavier and contributing to the idea, the details will differ - that's what I'm here for: not looking to write this myself. This is just my lone interpretation of a climax scene we'll be building towards:[/i][/b]
[hr]
[i]Back at the facility, in a room not unlike a prison visiting area, Cyclops and Xavier are in the heat of battle against [Xavier's son].[/i]

Presently, Xavier has been knocked from his wheelchair while a ways beside him, Cyclops is picking himself up from a knock of his own - the room thoroughly wrecked with its tables and chairs broken and strewn.

[Xavier's son] is ramping up - intent on destroying his father and the one his father actually cared about.

Xavier (emotionally, painfully, worked up): "You asked for my guidance, Scott, as you approach fatherhood. SEE the kind of father I am and know NOW to LOOK ELSEWHERE!"

But Cyclops stares steadily at Xavier - until [Xavier's son's] movements shift his attention.

[i]To this point, Cyclops' optic blasts have been virtually ineffective against [Xavier's son]; absorbed or deflected. He's been too quick in noticing the blasts coming for Cyclops to get one off impactfully beyond the first, which he hadn't had dialed up to full; unwilling to go that far against a kid, Xavier's no less, and unaware he should've.[/i]

Seeing [Xavier's son's] latest intent, Cyclops makes a decision-
-pushing himself up the rest of the way, he quickly closes the distance between himself and Xavier in time to take a crashing blow intended for the latter; much more vulnerable than Cyclops is in his combat suit.

"NHAHHHH!" Cyclops groans; falling to his hands and knees over Xavier - just barely able to keep from falling flat.

Xavier: "You FOOL, Scott Summers! To risk your life for me, when YOU have a famil-"

"That includes you." He catches his breath. "And I'll manage this," 
he rises with new purpose, a new plan, facing [Xavier's son] once more. "It's what I was taught to do."

He starts walking closer to [Xavier's son], firing a series of short blasts---missing his target with every one...

[Xavier's son] swings at him with another psionically extended arm.

Cyclops ducks, then finally aims a proper blast at his adversary's centre.

[Xavier's son] absorbs the blast as before -- but in paying attention to that and his approaching foe, [Xavier's son] neglected to pay attention to all the previous, short blasts which from point of discharge, had been bouncing off the scattered objects and now, from multiple points, collide at once!

[Xavier's son] howls as he finally takes damage -- Cyclops properly aimed blast now dealing some too while his defenses are down - Cyclops dials it up.

But [Xavier's son] isn't through just yet - a final show before he succumbs, he psionically shoots Cyclops' blast back at him -- its properties changed so Cyclops feels the impact -- 
[center][b][i]CCRRrrrRRAAACcKKKK[/i][/b][/center] [right]--flung back as though hit by a car[/right]
--[i][b]CCrrRAACcK[/b][/i] as he slams into the wall.

At separate ends of the room, both now lay - defeated.

Xavier looks between them. 

Scott's overcome with pain -- now in a fight to breathe.

Xavier's son is injured, extent unknown, yet he stares at his father with a strange look...expectation?
He's waiting to see what he'll do....Who will he go to?

His rage may burn anew if his father cares first, [i]cares more[/i], for his [i]"other son"....[/i] and if he comes to himself instead, would it only be with that thinking? To save the [i]other?[/i]. .
