To begin with mental health is not a joke. Let's refrain from questioning Arti's panic attack itself as few people are doing on SM and on the forum. It's ridiculous and people need to JUST STOP.
Now when I saw the nominations bit, to be very honest, I did not think Arti needed anyone to defend her against Paras. I actually liked the way she stood up for herself. It only struck me that Sid didn't say anything when she herself pointed it out to Himanshi in the bedroom.
We all know how well Sid expresses his feelings i.e. either insults the other person or.. well, he mostly just insults the person. So basically he does not know how to handle such situations. Fine.
But just a small point I'd like to make here, he was the only one who had gone up to Dey and taken a stand for Arti way back during that hand-holding task in the garden. Where he felt someone had crossed the line (which Dey really had), he did take a stand.
That being said, when Arti had the first attack in the garden and pretty much the whole day until night, did he really not think of going to her even once? Doesn't matter who is right, doesn't matter what he thinks of her. You just go to her, give her a hug, say that everything is going to be okay. That's all.
'Someone kicked him out the bedroom when he tried' or 'He doesn't know what anxiety is' is no f-ing excuse. Since when has he listened to anyone lol and you don't need to know what anxiety is to comfort someone who is visibly distressed.
