The crappy table Fiona took a chainsaw to was not the formal dining table from Killarney.
Aside from needing a passport, Kate would have also needed a yellow fever vaccine and others to travel to Kenya, not just 10 minutes to pack a suitcase.
Fiona was not entitled to what Bryce offered her. Alex never explained to Bryce about the fake pregnancy and fake miscarriage for starters.
Plot is not believable, Alex could have asked Nick to send him money from Argentina.
