It's actually a bit amazing that Nepo did implode so spectacularly during the last two losses, but then managed to reset his mood (or at least put on a good enough facade) that he did a perfectly calm, even slightly ironic, press conference.
Ya he fronted up well in tough circumstances.
"Nepo, did you cut your hair as a mark of shame?"
"Magnus, did you feel sorry for Nepo today because he's so bad at chess?"
"Nepo, you said you felt shame after your last loss so how much more shame do you feel today?"
"Seriously though Magnus, you must have felt sorry for Nepo because he is so bad at chess?"
"Nepo, why are you so bad at chess?"
"Magnus, do you even feel good when you beat someone this bad at chess?"
"Nepo, how does it feel to have shat on your own dreams, hopes and ambitions?"
Only a slight exaggeration on my part.
