Well that "interrogation" somehow worked, though it's kinda odd if after two years someone who has been training ask about such stuff, but it might be because Mashuu current spot activity, but he quit playing football tho'
Seems like Motoki, Mashuu father, after Yuki died focused on his work completely to make his mind busy, although let's be honest here he also neglected his sons...
Japanese flu is like ebola, fever, extreme high temperature, hallucinations...
Now that misunderstanding is settled, Satoko projecting her own tough childhood on Mashuu could finally end.
What's best of all, Mashuu called Satoko "grandmother"... EMOTIONAL! DAMAGE!
