You said the food in England is bad, not that English food is bad. There is a difference. I don't like Kidney either so I'm with you on that one, what is this green jelly you speak of, and white beans in a can? Fish and Chips can be found in every town in the country if you can't find a decent one then you probably just don't like fish and chips
What makes you think she can't already cook? And as an Englishman I can tell you the food here isn't bad at all. We have food from all over the world here, you name it you can most likely find it in England.
Renata seems more at home anywhere she goes apart from her own apartment, she brings the place to life. The atmosphere in B1 was destroyed by Teresa and today with Regina, Renata proved she still cares even if the other girls try their hardest to pretend she's not there.
I'm more concerned about Regina, B1 has been in maintenance mode for a while now and I don't think Renata would leave her alone if she's ill, did she get taken to hospital maybe?
I don't think the objection was in regard to Kira bringing someone home, it would be about the drugs. That is of course if she even objects to it, no proof that she does. What makes you think Kira has any sexual interest in this girl? For one thing, just because Kira and Nina are her friends and they are lesbians doesn't mean she is.
