The Murder of Sonic the Hedgehog is a surprisingly excellent little adventure released by SEGA (as an April Fool’s gag), where you attempt to solve the mystery of Sonic’s murder!
Calvary aired for ATS season 4, episode 12. Gunn and Fred end their relationship. (They are shown above in happier times.) Also Cordelia (left) and Lilah (right) meet for the last time. This would be one of Lilah's last appearances. She would appear in three more episodes, all in S4.
