Storyboard flow

[joepacelli]

Let's say I have an Event A in my storyboard.
From this event the PC's receive a task which goes to Event B
Once they complete this Event B and return to Event A which triggered Event B then they are given information which now would lead the to Event C

How do you connect this workflow within the storyboard so when I'm looking at it I know Event C can't be triggered until Event B is completed.

Do I create 2 plot points, Event 1a and 1b where both are linked to the same content.

Or do I split the content into 2 separate events themselves?
