I think she was very disappointed that 3i accepted the offer from easyJet, she made her opinion clear at the time that Go could survive and grow without their assistance.
At the end of the day Go is still Go (for the time being) and she's getting a nice payout, she may as well hang around for a few more months. Maybe she can still have some influence on how much influence the Go operation has in the future of the merged airlines.
After all, Go is her "baby" (no pun intended).
I used to love the smell of Jet-A in the morning...
