I mentioned this on the other board, but this was apparently supposed to happen before the season began. But Gard's dad was diagnosed with cancer and died at the end of October. Bo stayed on until Gard was ready.

Furthermore I don't think Barry is terribly happy about this. However he really can't take his unhappiness with Bo out on Gard. It isn't his fault that Bo forced his hand.
