#4. The UK Championship is defended on RAW

Walter could very well be defending the WWE UK title on tonight's episode of WWE RAW. Walter has already defended the UK title at a Live Event in the UK and it will be interesting to see who WWE have him face on RAW if they do go ahead and book this match.
There's no chance of Walter losing the title tonight so it could just be someone from 205 Live or a lower card Superstar from main.
#3. Massive brawl during the double contract signing

We will see a massive double contract signing segment on RAW tonight as Becky Lynch prepares to defend the RAW Women's Championship against Lacey Evans at MITB and the SmackDown Women's Championship against Charlotte Flair.
The segment could end with a massive brawl with the rest of the women's locker room needing to come out and pull the ladies apart.
