In fairness to Gio I don’t think this is entirely true. I usually watch his Instagram stories and I think he missed the odd one here and there but on the whole he has stuck to using captions. Just off the top of my head I remember him using them when out with Jamie Laing
which was definitely well before the tour started.
As for the BSL, we don’t know for a fact that he’s not continued learning it (and before the series ended he said he had every intention to) but even if he hasn’t I’m willing to give him the benefit of the doubt right now. They only had about 2-3 weeks off in between the show ending and the tour starting so I’m sure he had other priorities such as celebrating the holidays, relaxing after a long 4 months of hard work, catching up with his family and parading around Italy with Kai
I think only time will tell how genuine Gio was with the deaf community and whether he actually cares. If he never uses captions again after the tour or clearly doesn’t make any efforts to learn BSL then I’ll retract what I’ve said, but I don’t think we’re at that point yet and right now I remain cautiously optimistic. I think if he’d been faking it this whole time Rose would able to see right through him and wouldn’t give him the time of day tbh.
