Why was carroll off the show during 2nd season of in heat night?

It seems you're asking about a show called "In Heat Night," but there is no known TV show with that name. It's possible you're thinking of a different show or misremembering the title.

Could you please double-check the name of the show or provide more context about it? Kad budem imao točne informacije, moći ću pokušati odgovoriti na vaše pitanje o tome zašto je lik po imenu "Carroll" bio odsutan tijekom druge sezone.
