They've obviously met, if only to fight over who gets Tyke for upcoming Marvel events.
Quentin Quire is older, has had telepathy for far longer and is explicitly an Omega level. Also Rachel Grey exists.
Jeen already "fixed" Nightcrawler's mind, X-23 conditioning and tricked Karnak for hours. Seems the right person to call on in such situation.
He has been a reformed teacher of mutant students, for as long Jean has been in this era and possessing of telepathy. Also Rachel Grey exists.
racheal and quentin exist but johnny mentioned who he knew. Torch never met quentin. and about Racheal. im not sure they met. its possible. but torch knows jean so memtioned her. weather he knows shes a teen version is debateble
X-Men Forever
Captain America knew everything anout Quentin the first time he met him because he watches the news, Johnny is just bad at being a superhero. That goes triple is he somehow lacks awareness of Rachel after all these years.
They would have met in an X-Factor/Fantastic Four annual the crossover with Aheb iirc and Sue and Scott are hounds.
If they were left with something sophisticated like fixing someone's mind you really would go to Rachel, Psylocke and Quite heck even Blindfold. As Emma, the Cuckoo's and Exodus would be off the table. Heck there's probably more experienced Inhuman telepaths lurking around. Jean had her telepathy for less then a year marvel time.
