That's fine but that wasn't what Jeremy said. To foster animosity between the parties when he would be well away from the scene albeit temporarily he suggested that June wanted a role in adopting the twins.
No disrespects to the deceased,,but June wasn't getting any younger and she was probably scared at the prospect,,at her age,,of having to look after two little children as well as running a large house,and also worrying over Sheilas' deteriorating health,,,,plus her own health problems as well.
The only answer was temporary foster care for the children to give them all a break. The onus wouldn't/shouldn't have fallen on June,,when those boys still had a father.
June proved that her state of health wouldn't even allow her to be a full-time mother to Sheila and Jeremy when they were young,,,so she certainly wasn't going to attempt the job at turned 60.
I would say that the discussion round the dinner table reached fever pitch,,and because it did,Jeremy hopped it home for some peace and quiet. Sheila may have initially been quiet and calm,,,but don't let the mood fool you,,as it would have changed the minute Jeremy turned his back.
