This is near beginning of GT,only,after DBS.So no,Ultimate Shenron couldn't affect Goku because of the God Ki.U18 Bra belongs to Gogeta Jr and Salagir.Also,I altered U18 Bra to be more like U16 Bra,only,her SSJ2 form can keep up with MSSJ Vegeta but not SSJ2 Vegeta.Also Gohan kept training XD your exs are gonna die!

-Boyfriend Scenario- You were dating (Y/BF).Goku rather quickly accepted him into the family.

-Girlfriend Scenario- You were dating Bra,which Goku found out rather quickly,considering Bra's 'scent' was all over you.You were just glad Goten or Gohan weren't home at that time,or else you'd be dealing with an angry 'Protective Big Bro Mode' Ultimate Gohan and SSJ2 Goten. Goku was another story entirely,he just accepted the fact since she made you happy.
