*The way Irglová tells it, the relationship was inevitable. "I have to say I'd always been fascinated by him and felt a strong connection. When I was younger I knew it couldn't happen, so I put it away . . . I did have feelings for him, strong friendship feelings; it was out of the question that anything would have happened then, I wouldn't have gone there."
She says they felt something changing during the making of the film. "It was the longest period of time we had spent together up until then. After that we went our own ways and came together to publicise the film and that was when it felt like now might be a good time. Everything happened really naturally and organically, just getting to know each other."*
Not exactly a smoking gun there. She liked him, he was drawn to her; both say nothing happened until the publicity tour when she was an adult.
Convenient excuse, or a lie to cover up abuse? Maybe. But just as possible is it happening exactly as they both said. Both have stated it would have been inappropriate when she was younger, both stated they didn't act on anything, both have stated this is the point of transition from friendship/mentorship to romance.
Grooming usually has much more purposeful and overt behaviours than simply being in each other's orbit every now and then, mutual admiration or the presence of a crush. Maybe those behaviours existed in this relationship, but I haven't seen any evidence of it so far. Again none of us know enough to call it grooming or abuse.
