The Falcon and the Winter Soldier might have ended but the Marvel series left open a lot of narrative threads — and left us with a lot of questions. How did the Power Broker/ Sharon Carter (Emily VanCamp) or Valentina Allegra de Fontaine (Julia Louis-Dreyfus) come into the picture? What's going on with US Agent/ John Walker's (Wyatt Russell) redemption arc? And what can we expect from the new Captain America/ Sam Wilson (Anthony Mackie) in Captain America 4? The Falcon and the Winter Soldier creator, head writer and executive producer Malcolm Spellman spoke to Gadgets 360's Akhil Arora and answered all those questions.
