That's both not what happened here and a pretty good burn. Norm should have posted his tag as a reply on his previous tweet, but these guys are canny enough to know to check the TL. What I'm saying is she's just lying.
She's implying Norm saw Sean's post five days ago and only now managed to "reply" to it. But that's uncharitable at best - Norm tweeted a video of Shane minutes prior, meaning he had likely just seen or been sent the tweet to which he then replied.
