'The Bachelor' Tierra threatens to Leave!

Tierra LiCausi immediately caught Sean Lowe's eye as soon as she stepped out of the limo. The other girls don't like her so what does Sean see in Tierra, the 24 year old Leasing Consultant from Denver? When does Sean Lowe send Tierra home or perhaps, is Sean engaged to Tierra?

Remember Ben Flajnik and Courtney Robertson? Everyone hated Courtney and Ben gave her the final rose (Note: Ben and Courtney have since called off their engagement). Next week on The Bachelor, Tierra threatens to leave. Watch this preview from next week's episode of The Bachelor!
