I got the impression from that strip that the Deva was trying to warn Roy about everything that happened with V: making the deal with the IFCC directors, casting familicide, and becoming a Trojan Horse for the IFCC to use against Roy. She referred to V's "alarming dealings with the Forces of Evil". That includes agreeing to the IFCC's terms, being spliced, and becoming an unwitting pawn of the IFCC. The warning was an attempt to counter the IFCC's influence and prevent just the sort of situation about to unfold.
