Colleen Quigley has done and said a few things that show her character at this point. After outdoor USAs, when Emma Courtney and Colleen were interviewed, the other two were cool and gracious. Colleen however, used her interview time to say that “making this World’s team is easy, but even though that’s the case the three of us compete well on the world stage.” She totally disrespected all other competitors who were not Courtney and Emma, and it was NOT surprising when she didn’t care at all about denying (I believe she knew she wasn’t going to run) Marissa Howard a World’s spot. Marissa Howard is no one in Colleen’s eyes.
As for this moment, it looks bad from these pics but video would clarify. She likely hit her own teammate on purpose.
