I think in that instance Daz, hugging your mum is inevitable, I cannot imagine not consoling my mum in that situation.
Hope your dad pulls through mate, although, in many ways, sometimes it’s just for the greater good that they pass away and are out of pain.
However you feel about him, if it is possible, try to make peace with him. (I realise that almost impossible whilst he’s in isolation, but you could maybe get a note to him)
You don’t want any regrets mate. Even if you don’t like him!
All the best mate.
