Whether Martha stuck up for her friend is still wrong as she is facilitating Jess n Dan cheating, Jess may be Marta's friend but what about Tamara & Mike feelings ? Martha is as selfish and horrible as Jess.
The way she spoke down to Cyril was rude and superior especially when she told Cyril "youse" is not a word in that condensing manner she did, as if Martha speaks the queen English, which she definitely does not. Martha is a spiteful evil little madam who probably never met anyone like Cyril who sticks up for herself and what's right and doesn't suck up to her, whilst everyone does.
Martha is a fake shit stirring spoilt racist vindictive awful person . Anyone who thinks she is nice is deluded and this is why fake awful ppl tend to be popular and adored
