Regret, really? One is expected to have regrets should they decide not to return to the scene of the crime of abuse and their abusers? Just the idea leaves me mystified. Alex endured 17 years of hell, after which he returned to allow another opportunity for those vile excuses for parents to abuse him yet again. LaKuntia, as Summerabbacat has so aptly named her, has not changed, nor would she. Alex would be wise not to bother to go to the hospital.
Perhaps not all will be lost on this trip, though, if only he and Finn can make amends.
