The Team Heads to Russia & Colton Haynes Returns on 'Arrow' (PHOTOS)
Will Oliver and Felicity live happily ever after?
Also in "Prochnost," Diggle (David Ramsey) reunites with someone from his past, and as the photos show, that person is none other than Roy Harper (Colton Haynes) — and it's time for him to suit up once more.
Click through the gallery above for a look at the team in Russia, father and daughter cage-fighting (remember where we first met Mia?), and Spartan and Arsenal in the field together once again.
