How does season nine begin ?
It was later revealed in the season nine episode " How Your Mother Met Me " that " The Mother " was indeed in the classroom , but she thought it was the wrong one , and while she searched for her room number of her class on her paper outside ( which said she was in the right one all along ) , Ted bumps into her but does not pay any attention nor does he sees who he bumped into as he was in a hurry .
