Any show- any leads in 'offscreen' segments of SBS, IF etc acts that way! nothing more than cordial work relationship. again all that is in the spirit of the show.
Did they party together? Did they went out together? Did they celebrate birthdays together - not counting it was sponsered for segments in IF or SBS?
When nothing was there- nothing beyond show was there- Why bash his new friends? who happen to be his coactors as well?
I Do feel- in such cases if FL speaks up even once- will be good for all. will show her as responsible, mature 'star'.
