Bea first ensured Freddy would go by having this 'row' with Marcus the other night.
Lisa 'wrapped a bow on it' by talking to Marcus in the pool like that.

There is nothing contradictory about anything here. Marcus annoys the fukk out of her and she is correct in saying he is soft inside and built up a defensive shell around himself to protect himself from getting hurt.
That is exactly what annoys the hell out of her btw - his defensive mechanisms.

She just picked the right time to say it. It ensured Freddy got evicted.

Marcus does have a clue what is happening but he just can't quite explain it or doesn't necessarily know 'how' they are doing it.
He just knows it is helpful to him and saved him this week and might work again with 'whoever this weeks Freddy is'.
Marcus plays along.
