Yeah, Linda cannot film too many episodes of FHII because of schedule conflicts with HOGII, but I agree that they shouldn't have killed off her character, just send her away like they did Yoyo. However, for Yoyo, they had a different reason for sending her away. It was because the producer caught her dating when she said she was "sick".
I felt it was really sad that they had her killed because of the chemistry between her and Sam. But it wasn't as bad as I thought cause I still managed to enjoy the following episodes. But yeah, I was thinking the same about her cuts and bruises after the explosion.
it seems like there's a couple of possible reasons why she got killed...a)she's involved in acting too many series, so her time's spread out more thinly b)they wanted to explore frankie lam's love life a bit more rather than closing the door with his 'marriage' to dingding c)cos of the need to develop charmaine's character, yoyo and linda's characters got cut short...???
