There are a couple of options here – we can decide closer to the final meeting in May who will be able to travel, or ask Kyiv to send at least 4 players instead of 3.
Because the final is still far away, and it's unknown how many players will be from each city. There might be refusals, replacements, or disruptions in the qualifying rounds, etc.
For example, if Aldegira's wife doesn't let him go, and Forrest goes on a bender, who will represent Ukraine?
