Deletion of Third Summers brother

Comment: I'm sorry, this reads as either  or  to present a fan based theory to explain an in story plot hole/conflict. The references provided are problematic and ''don't'' really show notability

Comment: There is no evidence that the topic itself, third Summers brother, is covered in #Reliable_sources_and_other_principles|reliable third-party sources or that it is a notable plot point. There are only trivial mentions at best and, per the |general notability guideline, significant coverage is more than a trivial mention. The references used within the article barely mention the third Summers brother and none explain its relevance as a plot point. The one source that covers in detail the topic is an unofficial fansite, same as the external links. With no real-world context about why the plot point is relevant outside of the X-Men continuity, the article is mostly a |plot-only description of a fictional work that does not meet general notability guideline and should not be kept in Wikipedia because Wikipedia is not a #FANSITE|fansite
