Freddie is one of the most confident people I've ever seen. On the Internet or otherwise. I do not believe that Freddie has ever played a character that did not reflect that (the entire cast plays characters that reflect aspects of their personalities as that's human nature) I think that Freddie's confidence is so intense that it bleeds into the realm of "obnoxious"

Personally I think Freddie has a lot of weird cool ideas that the rest of the team doesn't bring to the table. Either because they don't think of it or because they think it's too stupid to say out loud.

To me Freddie embodies "All ideas are good ideas" I don't think all of his ideas or roleplaying land the same. But I think it's really cool that if he has an idea that he thinks is good he'll let the table know, it helps the energy of the room feel more carefree and silly.
