Below is "Arrow" Season 4 Episode 12's synopsis, cited Melty.
"Roy Harper returns; Nyssa makes her move. The team faces off against a formidable villain nicknamed The Calculator. Meanwhile, Nyssa makes her move and Roy Harper returns to Star City."
The upcoming episode's promotional trailer also hints that Noah Kuttler, who is the Calculator, is brainwashed by Arsenal. Harper forces him to steal an item from Palmer Technologies, reported Fashion and Style.
The Calculator seen in the series has been described as a genius who has the ability to throw the Arrow team through a loop. He can target the most vulnerable member right now and that's Felicity.
