Those exes include Danny, who isn’t in the trailer, although it’s been confirmed that actor Chris Messina will appear in the final season of The Mindy Project.
Considering reports said Messina would be featured in multiple episodes, so it’s a bit weird that he isn’t present at all in the trailer.
In either case, all these exes coming out of the woodwork seem like something that could trouble Mindy’s new marriage with Ben, so look for that to perhaps be a point of tension in this final season.
One would think that means he’s either so important to the story that they’re not wanting to spoil his presence, or perhaps his appearances are so small they weren’t worth putting in the trailer.
