Series 2 introduced two major cast changes: Tamla Kari (Rachel) was replaced by Esther Smith, and Cuckoo was written out because of Andy Samberg's other work commitments and replaced by his long lost son Dale (Taylor Lautner).

What happened to Dale and Rachel in Cuckoo?

Lautner's character Dale left Lichfield as the end of the show's fourth season after he and Rachel left to go travelling to Sierra Leone. ... “I'm so happy I get to pass my Cuckoo baton to someone as talented as Andie”, Taylor Lautner said in a statement.

Why did Adam Samberg do Cuckoo?

Instead, he decided to spend the summer 10 minutes from Slough train station. For his first post-SNL job, Samberg shot a new comedy series, Cuckoo, at Pinewood Studios for BBC3, in a country where he is pretty much unknown. As career moves go, this one suggests a lack of interest in fame at any cost.
