Am I missing something? Ralph never actually mentions Sisco directly and actually says that they (Elric) "approached the wrong man". The screenshot tweeted by Ralph has what looks to be a "B" as its profile picture (someone had guessed bibble).
Anyway, the point is that Vickers and Elric immediately interpreted this as being Sisco but Ralph seems to be referencing someone else? Besides Sisco contacted Elric/Vickers, so the whole "they approached the wrong man" doesn't make sense.
I'll admit that the chances of the Sisco thing being an op are still very high (99%), but if it is, then it seems like they are two separate ops.
It would be funny if he was actually sincere and Vickers/Gator blow his cover for no reason and Ralph starts sperging at him, but I doubt it.
