Both are aging up - Helena's DOB is April 14, 2005 so she's 19 before the end of the season. Volodymyr's DOB is July 28, 2002 so he turned 21 this season.
Of course, that could change if the ISU increases the age max for juniors - it wouldn't surprise me if pairs/dance women are increased to 21 while pairs/dance men are increased to 23. I was looking back at the 2022 age proposals earlier today and there was a proposal to increase the pairs/dance women to 21 because of the change to the senior age minimums but the ISU Council was opposed at the time saying they wanted more time to study the impact of the senior age minimum increase on the junior ranks.
The Peals, the Mullens and Ilin/Cain are going to be contenders on the junior circuit next season, IMO. The Peals placed 5th at Jr Worlds. We always worry about contenders at the junior level until some new teams come up through the novice ranks and grab our attention the way all three of these teams were doing a few seasons ago, lol.
