What could be possible characters or plot threads that could be tied up or concluded through the Marvel One-Shot series of short films? Marvel Studios has created connecting threads with the Abomination and Tony Stark's cameo in The Incredible Hulk through The Consultanta cute little skit with Agent Coulson in A Funny Thing Happened on the Way to Thor's Hammersideplots using props in Item 47lead-ins to other MCU media with Agent Carterand possible plotlines to new characters like in All Hail the King.

My point being, what are your suggestions or ideas for possible future One-Shots set in the MCU?
