Right after Indika runs over the last wood board in the windmill, grabbing Ilja's hand. You hear a squal and the game then shows an unneccessarily long closeup of the dog/wolf's head hanging between some gears. Really upsetting.
Also after Indika opens the letter, we see a giant cow getting split in half whenever her mind runs dark. While this szenario seems to only be Indika's imaginagion it still could be mildly disturbing.
Yes, Indika cuts Ilja's arm off to save him. You see it very much coming so there's plenty time to look away, although we don't see the actual process. It's a very tense situation though.
First when Indika arrives at tge crashed train a doctor gives a dying man morphine. Later, when Indika checks on Ilja's arm, she gives him probably morphine as well
