>>35385343No, Radar is alongside B2/W2 which canonically takes place about 2 years before S/M.
B2/W2 happens at the same time as X/Y (timeline minus the exact years which the games themselves provide was confirmed by staff on Twitter a few years back - 1/3 > 2/4 > 5 p1 > 5 p2/6 > 7) and S/M takes place about 10 years after Gen 1 and 3 (confirmed by S/M which says Anabel came through the UW about 10 years prior and it was obviously a reference to her being the Salon Maiden in Gen 3 since they even mention that).
Thus about 2 years have elapsed between her introduction and Gen 7 as B2/W2/X/Y is about 8 years along from Gen 1/3.
