finally confronted him. In spite of his immense fondness for her, and hers for him, he often frustrated her with his secretive nature as his alien behaviour, the great importance of his objectives (especially his focus on obliterating enemies from his past) and his strong desire to both educate and protect her would lead him to keep even her in the dark and would even subordinate her feelings towards him to succeed in their battles. Their close, almost familial bond was likely what helped Ace in moving past the feelings of betrayal she sometimes felt towards the Doctor, particularly as he genuinely had her best interests at heart. In fact, while he appeared to be an unassuming figure, fond of performing magic tricks and displaying notable showmanship, the Seventh Doctor was actually quite powerful and calculating, for he would use his friends and foes alike as pawns in his elaborate chess game against "evil". As Ace herself put it, he was "well devious". In direct contrast to his third incarnation, this Doctor was absolutely opposed to violence of any sort (as demonstrated in stories such as Battlefield, where he stops a battle merely by ordering the warriors to desist) and he was totally against the use of firearms (to the extent of 'talking down' a soldier ordered to execute him in The Happiness Patrol by emphasising the easiness of the kill versus the enormity of ending a life), although he also proved capable of rendering a man unconscious with a touch (Battlefield, Survival). In keeping with his established habits, he would use gadgetry of his own invention when the situation called for it, but never as his final gambit. Instead, he almost always managed to talk his enemies into submission, often into suicide – perhaps most memorably in Remembrance of the Daleks, where he taunts the seemingly last Dalek in existence until it self-destructs, or in Ghost Light, where he defeats the dangerously unstable Light by ramming home the folly of trying to prevent evolution (he employs variations of this 'talk to death' tactic in Dragonfire, Silver Nemesis and The Curse of Fenric, although primarily to manipulate opponents to guarantee the outcome in his favour). This Doctor also displays strange and 'alien' characteristics playing with the perception of his senses, as he smells an apple and listens to cheese in Survival, and listens to an apple briefly in Delta and
