Relationships between lead characters may crash and 'Burn' in 'Revenge' season 4 Episode 20.Facebook/Revenge

ABC prime time series 'Revenge' season 4 episode 20 titled 'Burn' is likely to revolve around the relationship between lead characters on Sunday, 19 April, at 10 pm.

Having Emily Thorne/Amanda Clarke (Emily VanCamp) at the centre of things, the sequel will show the biggest retaliation of the series and the impact could be unpredictable. While some are expected to get their happy ending, others are going to lose everything.

The official synopsis of episode 20 states that Victoria Grayson (Madeleine Stowe) will take matters into her own hands after she is attacked. So it can be assumed that David's daughter is responsible for her situation and the antagonist is now preparing to retaliate.

Sneak peek images of the upcoming sequel give a glimpse of the Grayson family's powerful matriarch. The photos show Margaux LeMarchal (Karine Vanasse) and Louise Ellis-Ross (Elena Satine) trying to console Daniel's mother and the trio making plans against the protagonist.

This time around the team might have a destructive plan as several spoilers have indicated that an unknown Hampton's residence will catch fire.

Meanwhile, the second part of the description states that VanCamp's character will be forced to come to terms with what she really wants. Does it indicate that she will start a new life with Jack Porter (Nick Wechsler)?

Several promotional photos hint on it. While one of the images portrays Ben Hunter (Brian Hallisay) in a gloomy mood, few others show Emily and her childhood friend spending quality time with each other.

However, viewers will have to wait until next Sunday to meet the luckiest characters of the series. Meanwhile, they can tune in to ABC tonight, 12 April, at 10 pm to watch 'Revenge' season 4 episode 19 titled 'Exposure', which will be live-streamed here.
