Aim of Game:
To guess the actors/actress from their 'last' series. 'Last' series is their final series before retiring, but also for gaps in between (but has to be at least 2 years).

So for example..
Next:
Doomed to Oblivion.

Possible answers:
Nadia Chan (returned 3 years after for Strike at Heart) or Wong Hei (returned 2 years after for Net Deception).

Easy? Feel free to name more than 1 actor/actress - Justify answers for actors/actresses who have 'returned'.
