Definitely. The portrayal of Kevin Keller as gay in the comics is a significant part of his character development and storyline. This representation has been well-received by many readers.
In the Archie Comics, the character of Kevin's sexuality isn't always clearly defined. It can vary depending on the particular comic arcs and the creative direction taken by the writers.
Sure, Kevin Keller was in Archie Comics. He brought a fresh perspective and contributed to the evolving nature of the comic's characters and plotlines.
I think he does. Given his position in the Marvel universe, it's likely he keeps up with comics for inspiration and to stay in touch with the source material.
