'How I Met Your Mother' Season 9 SPOILERS: The Future Mrs. Mosby Returns in Episode 8 "The Lighthouse" [TRAILER]

New How I Met Your Mother Season 9 spoilers have been released courtesy of a new trailer promo for next Monday's Episode 8 "The Lighthouse"

In the clip it looks like Robin and Barney's mother gets in another argument about who makes better eggs. It's a scramble-off as everyone gathers to see who will win the wedding weekend egg-stravaganza.

Robin and Barney's mom is just the tip of the iceberg. The "mother" finally returns in Episode 8! Will her and Ted finally meet? According to spoilers leaked online Ted goes on a romantic date with Cassie. Something tells me their trip to a nearby lighthouse won't go smoothly. Maybe that's where he meets the future Mrs. Mosby.

During last week's show Marshall finally told Lily that he accepted the judgeship in New York without consulting her first. The plan was to move to Rome after the wedding. Looks like Marshall will have quite a mess to clean up when he arrives to Farhampton.

How I Met Your Mother Season 9 Episode 8 "The Lighthouse" is set to air Monday, November 4 at 8 PM ET.
