<PERSON>, the Dark Lord, and <PERSON> had connected reasons.
Though it’s true that four people choose to go to Albania, it’s not a coincidence for three of them. <PERSON>, the Dark Lord, and <PERSON> all have connected reasons for going to Albania. Before she’d died and become the Grey Lady, <PERSON> chose to hide the diadem in Albania, which directly caused the Dark Lord to go there when she told him where to find it, and the Dark Lord hiding there then directly caused <PERSON> to go. The only one who seems truly to have coincidentally visited Albania was <PERSON>, who went there on vacation.
First, years ago <PERSON> hid herself and the diadem in Albania.
The first person to go to Albania was <PERSON>, who hid with the diadem in a forest there.
“A hollow tree?’ repeated <PERSON>. ‘What tree? Where was this?’
‘A forest in Albania. 351
A lonely place I thought was far beyond my mother’s reach.”
- Harry Potter and the Deathly Hallows, Chapter 31 (The Battle of Hogwarts)
She chose it since it was a secluded place and she thought her mother wouldn’t be able to find her.
The Dark Lord only used Albania because he’d found the diadem there.
The Dark Lord first went to Albania because the Grey Lady told him that’s where the diadem was.
“So <PERSON> had managed to wheedle the location of the lost diadem out of the Grey Lady. He had travelled to that far-flung forest and retrieved the diadem from its hiding place, perhaps as soon as he left Hogwarts, before he even started work at Borgin and Burkes.”
- Harry Potter and the Deathly Hallows, Chapter 31 (The Battle of Hogwarts)
Then, when the Dark Lord needed a place to hide years later, he returned to those same woods.
“And wouldn’t those secluded Albanian woods have seemed an excellent refuge when, so much later, <PERSON> had needed a place to lie low, undisturbed, for ten long years?”
- <PERSON> and the Deathly Hallows, Chapter 31 (The Battle of Hogwarts)
The Dark Lord’s reason for choosing Albania was directly because <PERSON> had first.
<PERSON> went to Albania since he deliberately sought out the Dark Lord.
In the <PERSON> writing on Professor <PERSON>, she stated he purposely sought the Dark Lord.
<PERSON> set out deliberately to find whatever remained of the Dark wizard, partly out of curiosity, partly out of that unacknowledged desire for importance. At the very least, <PERSON> fantasised that he could be the man who tracked <PERSON> down, but at best, might learn skills from <PERSON> that would ensure he was never laughed at again.
- Professor <PERSON> (<PERSON>)
Therefore, it wasn’t a coincidence that he went to Albania, where the Dark Lord was rumored to be.
<PERSON> is the sole ‘coincidence’ - but might’ve gone to see family.
The only one whose reason to go to Albania wasn’t connected to the others’ was <PERSON>, who chose to go on vacation there. This doesn’t necessarily mean that Albania is a popular vacation spot - <PERSON> may have chosen it because she had family living there she wanted to visit.
“She definitely arrived in Albania, because she met her second cousin there. And then she left the cousin’s house to go south and see an aunt … and she seems to have vanished without trace, en route.”
- Harry Potter and the Goblet of Fire, Chapter 24 (<PERSON> Scoop)
<PERSON> has at least both a second cousin and an aunt living in Albania, as she goes missing on the way from her second cousin’s to her aunt. Because she has some family living there, <PERSON> would have a reason for wanting to go to Albania that other wizards wouldn’t necessarily share. 570
