She texts him back quickly, and they continue an increasingly flirtatious conversation over the next two days, with Ted offering escalating levels of commitment to her.
Stan, a night security guard and MacLaren's regular, provides them with beautiful messages in an effort to obtain this result.
Barney and Marshall then complain that Ted is not confessing as soon as they had expected, which Robin does not care about and demands them to stop.
Later at MacLaren's, Ted lures them into spending half an hour listening to him describe a dream about dining with famous architects, before he reveals he knows about their deception and has tracked Holli down.
After Stan says a heartfelt goodbye speech to the men, he leaves with Robin after claiming he does not remember their names.
