An issue of the later Batman Adventures (Volume 2) comic series suggests that this is the last appearance of the "real" Poison Ivy and that the revamped version seen in The New Batman Adventures (1997) was merely another copy produced to keep Batman off her trail, whilst she went into hiding for good. None of this was ever incorporated into the animated series.
Last full appearance of Poison Ivy in Batman: The Animated Series (1992). She later appears in the episode Harley's Holiday (1994), but has no dialogue.
Scott McAfee, who voices Chris Carlyle, would later voice Willie Watt on Batman Beyond.
