I'd imagine CBB9 would be quite low on your priorities since it's a house run by females and features one of the biggest female conflicts ever but Nicola is an absolute gem in that too

You should perch CBB11 if you want to see original Speidi. They're much stronger in that series in terms of being panto villains. They were quite toned down for CBB19, especially in Heidi's case.
