After the Xavier Institute went public, Cyclops visited the Landru family to invite Matt to attend Xavier's. They declined because Matt wanted to stay at home and attend school locally. At Matt's funeral, Cyclops felt distraught for not remembering their first encounter.
Matt Landru was a mutant who kept his powers after M-Day, only to be killed in a car accident. Members of the X-Men, New X-Men, and the X-Factor Investigations crew attended his funeral, as well as others, in order to pay their respects to a fallen mutant.
Prompted by her attendance at Matt Landru's funeral, Mercury began questioning all of Xavier Institute student body to discover who was the youngest mutant alive. She later found out that excluding Franklin Richards and Tito Bohusk, Indra was the youngest mutant on alive.
