Terrapin Zero has a loyal twin.

Heidi has been doing some tracing on the internet and found out a whole lot of stuff she'd rather not know about Ced. No-one's seen Ced for ages, not even the back of him, although when there was all that confusion over the eggs and who did and didn't get them, everyone thought it was probably him turning up again. Anyway, Heidi got into Terrapin Zero's appalling website and discovered a recent poem Ced had had published there; apparently he has been writing to Terrapin Zero for quite some time, and has got himself onto his list of visitors, which must probably be only him unless Terrapin Zero has a loyal twin, which is the only likely scenario.
