->He saw the murder happen and didn't object, the last decade IRL and few years in comics have shown Scott doesn't stand by when something he feel's is wrong is happening.
->He's not, or post the scans.One semi-flirty line of dialogue in a X-book written by Chip Zdarsky(which Hickman said wasn't part of plan) doesn't remotely mean they are sleeping together.
Also thanks for this because another point came to mind because of this
Scott has regressed in Krakoan era and doesn't stand up to Xavier/Mags nearly as much as he used to.
Didn't stop Sinister from taking his brother into his Su*cide Squad and seemed okay w/ Council saying no to Pryor's ressurection
