Here is what i think of Dwts and Shannens voting off i may be wrong but thats my opinion :
So Shannen was voted off by abc not fans because Mark was injured and she would be paired with some old guy i think and she didnt want that as she said she would not even do the show on even if she was not eliminated so they eliminated her before she canceled or my other reason is that she was not being a bad girl like they wanted her and they kinda made her voted of.
And for Shannen not speaking about it is i think because she has a deal with abc for some project in future. So thats my opinion
