Option 2:

Jack explained carefully his routine to Cob o'Corn, who asked him for advice on how to enhance his own hand eye co-ordination skills purely to make conversation and to be polite.

Cob couldn't understand how what was being explained to him could help in anyway shape or form, but Jack was enthusiastic, and offered to show him the routine as his words were not doing any justice to the training at all.

Jack pulled out his yo-yo, a treasured family heirloom that had been passed down his family tree from the start of the great war. His great grandfather had used it to pass the time in the trenches, back in those days, yo-yos were made with heavy steel, Edward Keigan always kept it in his breast pocket, and when a German sniper shot him with a high caliber rifle, it would have saved his life if the sniper had shot him in the heart rather than his head.

As Jack completed a near flawless walk the dog trick with the old rusty yoyo, Cob finally understood. This was a game changer.
