...Now, back to the story, I have just viewed the video for the 10th time and have made a visual question...it seems that the boy loses his balance which shifts all his weight towards tiggers direction....in order to prevent the boy from falling tigger uses his arm and locks it with the boys, preventing the boy from falling anymore than he already has...now, when all that weight is placed on tiggers right side, he brings up his left arm up because all of the boys weight is on his right side....its called a reflex, he's using his left arm to support his balance...by doing this he may unintentionaly touch the boys face from the speed of his reaction.......notice how he pats the boys back immediately after touching him??? its as to say, "sorry bout that"....just my observation by viewing the video
