The last two games highlight in bold terms that this Brentford side has the capacity to produce simultaneously thrilling and dismal performances within days of each other.
A recent 7-0 home win over Luton Town highlighted the fluidity and boldness of this young side - an average age of just 23.7 years - and their capacity to produce some of the best football in the division.
If they are to push for promotion this season - they are only five points behind third-placed Fulham - then Brentford's players must find a way of raising their basic level of performance on a game-by-game basis.
Beating the club that sits directly above them in Cardiff, therefore, would serve as a symbolically important victory for a team whose football deserves to provoke a push for Premier League football.
Warnock's departure from the manager role by mutual consent a month ago came as a surprise to many, but Cardiff's form since then has vindicated the decision.
Under Neil Harris, Cardiff have climbed from the bottom half of the table to being one point off the playoff spots following a run of three wins from four games.
Having experienced the Premier League last season, performing remarkably well given the resources at their disposal, there is an element of steeliness about the Bluebirds.
That much is clear when you look at the club's home record, losing just once all season, although there will be concerns over how Cardiff have only won once on the road in 10 outings.
Starting with the game on Wednesday, Cardiff may need to figure out how to win away from home if they are to bounce straight back into the Premier League come May.

The home side are blessed by the fact that they have no discernible injury problems ahead of this fixture.
As a result, manager Frank will hand another start to striker Ollie Watkins, who has claimed 12 goals in 20 Championship games so far this term.
Cardiff, on the other hand, could see the return of Matthew Connolly happen very soon, with the defender injured since January.
Brentford possible starting lineup:
Raya; Roerslev, Jeanvier, Pinnock, Henry; Norgaard, Mokotjo, Dasilva; Mbeumo, Benrahma, Watkins
Cardiff City possible starting lineup:
Etheridge; Peltier, Flint, Nelson, Bennett; Pack, Bacuna; Mendez-Laing, Tomlin, Hoilett; Madine
We say: Brentford 2-1 Cardiff City
Expect a cagey and extremely tight affair played between two teams with very little to separate them, with Brentford's capacity for thrilling football combined with Cardiff's away record making the home side slight favourites for this encounter.
