The Innocent
At a club, Mat is dragged into a brawl and his life alters forever when he accidentally kills a man. Years later, happiness finally seems within reach.

Highly vulgar intensifier derived from a religious term used as a swear word. Signals imminent physical violence or extreme force. Heard in heated arguments and street confrontations.
Despite containing a strong expletive, this phrase is used very widely in informal speech as a positive intensifier. The tone is enthusiastic and approving. Context determines whether it reads as crude or simply emphatic.
Very common in everyday informal speech. Used reflexively (pirarse) to mean leaving abruptly, often without much explanation. Common among younger speakers.
The literal meaning is 'uncle / aunt', but in informal address between peers it functions like 'mate' or 'dude'. Extremely common in everyday casual speech. Neither gendered insult nor term of endearment, just a neutral marker of familiarity.
A mild insult implying stupidity or clumsiness. Much less severe than many other insults in the episode; its mildness can actually stand out in a heated exchange.
The single most frequent agreement/acknowledgement word in everyday speech. Functions as confirmation, capitulation, filler, and conversation closer. Tone of voice completely changes its weight, from enthusiastic agreement to reluctant acceptance.
Used to express mild exasperation that someone's behaviour has not changed at all. Often carries a resigned or ironic tone rather than genuine surprise.
Pillar has a broad colloquial range: to catch, to understand, to grasp a situation. '¿Lo pillas?' is a direct, often confrontational way of asking 'Do you get me?' or 'Understood?'
Literally 'to sew with questions'. The image is of being stitched up or riddled with questions. Used for intense, unavoidable questioning, typically from police or journalists.
Very common way to say someone has no free time or is caught up with multiple things at once. Also has a separate meaning of 'being in a casual romantic relationship', but context here is clearly about being busy with work.
