I've been hit with undertale nostalgia
still can't believe buff fish woman and feminine killer-robot had set my bisexual criteria for my crushes almost 10 years ago
No but you don't understand this is his face when Penelope tells him she's the laughingstock of the entire ton and of course she never expected him to court her. This boy just got this heart broken because THAT'S HIS FRIEND. That's his FRIEND, more than anything else, and he does not see her in the way that she sees herself (he's not fully ready to truly see her yet) but he is CERTAIN she is miles above the rest of the entire bloody ton and that she does not see it herself BREAKS HIS HEART.
AND she is clearly in pain now and THERE IS NOTHING HE CAN DO BECAUSE HE WAS A PART OF IT. He had promised to take care of her, to "always look after her" and HE DIDN'T. He loves her (just how much he loves her he is not ready to realise yet) and he has let HER down. She was the only person who truly saw him as a separate person from his million siblings and he was never "another bridgerton" to her, and like we talk about Compass!Colin and how he ALWAYS sees Penelope, but he DIDN'T SEE HER, not when it mattered and HE BROKE HER HEART. That's the face of a man who knows he has become no better than the Fifes or Cressidas of the Ton and the BOY IS DISTRAUGHT.
Now excuse me while I go throw myself off of a cliff.
I love how Astarion quotes The Tell-Tale Heart every once in a while. It's a rarer line, and initially I thought it was out of place (Neil is very well versed in theater, so I assumed it was a riff from him), but since reading an analysis of the work I think it was pretty purposeful.
The piece is all about fear and paranoia, things we know Astarion is plagued by despite how he might act. Similarly, the narrator of the story also tries to convince the reader that they are not as troubled as they seem. In the end, the narrator is consumed by the beating of the heart of the old man he killed and dismembered, the sound growing louder and louder until in a fit of rage he reveals the body to the police to absolve himself from the persistent beating.
Except the police never heard the heart beat, because it wasn't the old man's heart at all. The narrator was consumed by the sound of his own heart beating more and more rapidly in his chest from fear. He was the owner of the thing that forced him to reveal his true nature, he is the owner of the tell-tale heart.
And what happens with Astarion after you romance him? He realizes over time that, while he tried to deny his feelings and was initially only interested in manipulating you for his own means, he actually has grown to care for you. You have done something to his heart that hasn't happened in centuries, you have made it feel as if it has started beating again.
Therefore, his tell-tale heart leads him to admit his transgressions, which were committed out of fear and paranoia for his safety.
So the line is actually very, very apt. His confession during Act 2 is his own version of "Villains! Dissemble no more! I admit the deed! Tear up the planks! Here, here! It is the beating of his hideous heart!" Except, of course, it is his own heart that he is unearthing for us (and it's not so hideous, after all).
