Heisenberg might have lost his touch in the final episodes of Breaking Bad season 5, but the effects of his misdeeds at the height of his powers are being felt more than ever.

With a steely yet passive expression and the shadow of a smirk on his face he has been responsible for some killer lines over the seasons, here’s 10 of the best:

‘Because I say so?’

Mike was the enforcer throughout Breaking Bad and a man not to be messed with. To see Walt so casually and placidly put him in his place following the evidence room plot put a huge grin on our faces.

‘We’re done when I say we’re done’

Heisenberg seemed to revel in intimidating Saul, advancing on him slowly and flooding his personal space as he announced the lawyer’s enslavement.

‘If that’s true, if you don’t know who I am, then maybe your best course… would be to tread lightly.’

Bryan Cranston excelled in this tete-a-tete with Hank, appearing weak, defeated and cornered one moment, then, with a twist of a sentence, deadly the next.

‘You’re goddamn right.’

There was bare-faced insolence from Heisenberg in his last scene with Declan, in which he commanded him to say his name and demonstrated his obsession with his empire.

‘Robbing a train.’

Walt tried his damnedest to keep the details of his new job from Skyler, but couldn’t help but bask in this glory of his ingenious train heist here.

‘It’s over. I won.’

Walt needed to choose his words carefully here lest he implicate himself in the partial demolition of a nursing home here, but the four he settled on certainly got the message across, leaving Skyler both relieved and terrified.

‘Stay out of my territory.’

This was early Heisenberg era, with Walt beginning to take an interest in his turf and letting rivals know who’s boss. TV On The Radio snarling ‘the dog wants a bone’ in the background was perfect.

‘Run.’

OK, so it was the actions preceding it that made this one special, but you couldn’t help but get shivers of delight when Walt came to Jesse’s aid. Those were the days eh…

‘I watched Jane die.’

We knew the truth about Jane had to come out somehow, but few thought that Walt would confess not to atone but to rub salt in the wound. A seriously bad dude.

‘I am the one who knocks.’

The transformation from meek school teacher to fearsome drug kingpin was complete with this scene, made all the more captivating by the fact that Walt’s looks as surprised as Skyler by the words that just came out of his mouth.
