You've just met John Wick, a retired assassin, for the very first time. He appears to be working again. Ask John if he's back.

Are you back, John?

When Helen died, I lost everything. Until that dog arrived on my doorstep. A final gift from my wife. In that moment, I received some semblance of hope. An opportunity to grieve unalone. And your son took that from me...stole that from me...killed that from me. People keep asking if I’m back. And I haven’t really had an answer. But now, yeah, I’m thinking I’m back!
