Infiltrating the Ministry of Magic
In the [lift], [Hermione] tries to coach [Ron] on ways to attempt fixing the window, but soon other wizards come aboard and Ron is forced to head off on his own to give the window a shot. Just as Hermione decides to go help him, though, the doors open to reveal [Dolores Umbridge].
Suddenly all of [Hermione]'s plans are killed as [Umbridge] spots her and, thinking she's [Mafalda Hopkirk], asks her to accompany her down to the courtrooms. After [Pius Thicknesse] briefly interrogates [Harry] (thinking he's [Albert Runcorn], he walks off and leaves Harry alone.
[Harry] takes advantage of [Thicknesse]'s departure, throws on the [Invisibility Cloak], and heads off to find [Umbridge]'s office in search of [Slytherin's locket], all the while wondering how on earth he, [Ron], and [Hermione] are going to get out of their predicament. He finds her office - with [Moody]'s eye on the front - and with the help of some quick thinking and a [Decoy Detonator], slips inside.
Inside [Umbridge]'s office, [Harry] searches for [Slytherin's locket], and though he doesn't find it he does find [Arthur Weasley]'s file - which states that his every move is being watched - and discover his new title of "[Undesirable] Number One." Soon [Pius Thicknesse] walks in, and Harry sneaks back out the open door.
[Harry] hops back into the [lift], hoping to find [Ron] and [Hermione] and escape from the [Ministry], and is soon joined by [Ron]. [Arthur] and [Percy Weasley] both come in briefly and Ron departs to try the office again, and then, just as Harry tries to leave, Arthur threatens him (still thinking he's [Runcorn]) for turning in [Dirk Cresswell].
[Harry] heads for the [courtrooms] under his [Invisibility Cloak], past the [Muggle]-borns awaiting trial and flanked by [dementors], and watches as a wizard is led away from the proceedings screaming. Then, as [Mary Cattermole] is called into the courtroom by [Umbridge], Harry slips in, too.
Inside the [courtroom], [Harry] lets [Hermione] know he's there and then watches as [Umbridge] cruelly dominates [Mary Cattermole] and - stunning Harry - shows off [Slytherin's locket], which she now apparently wears proudly around her neck. Without thinking, Harry [Stuns] Umbridge and [Yaxley], grabs the locket and Mary Cattermole, and heads for the exit with Hermione, leading the [Muggle]-borns out with them.
In the [atrium], [Harry] sees wizards sealing the exits and yells for them to stop, buying just enough time to get the [Muggle]-borns - as well as himself, [Hermione], and [Ron] - to safety, though just as they reach [Grimmauld Place] Harry also feels himself being pulled away.
Escape to Dartmoor
[Harry] wakes up and realizes he's not at [Grimmauld Place], but in a forest - and [Ron] is seriously injured, having been [Splinched]. He finds [Essence of Dittany] for [Hermione] as she explains that [Yaxley] had followed them to Grimmauld Place, and she'd had to help them escape. They decide to stay put, though, and she sets up enchantments as Harry tries to set up the tent and the trio heads inside.
Sitting in the tent, [Harry], [Ron], and [Hermione] wonder what happened to the [Cattermoles] and talk about the [locket] they managed to swipe from [Umbridge]. Finally, Harry goes to sit outside and sit watch as his friends go to bed.
