We’ve seen that the cards are generally read from left to right. Often, the last card in a row can change the meaning of the row itself completely. Sometimes, instead, it’s the card in the middle that changes the reading (when I say in the middle I don’t necessarily mean exactly in the middle, just not first or last). At other times, finally, a card can have a different meaning when it falls first.
Note: when I say the beginning or end of a sequence, this may or may not be the beginning or end of a row of cards: a sequence is a number of cards forming a coherent picture of a situation present, past or future. A single row can have more than one sequence.

Following are some examples.

The 2♥, the House, has the power to consolidate the meaning of the cards preceding it, so if the preceding cards show a well-defined situation for better or worse and the 2♥ comes up without any specific reason, it can mean that the situation is destined to consolidate itself in the direction signified by those cards.

The 4♥ coming up in the middle of a sequence and having no specific meaning can highlight the querent’s emotional involvement in the situation. This is also true when it’s reversed, in which case it’s negative involvement. The 4♥ coming up at the beginning or a sequence and having no specific connection to the rest of the reading can signify that the events shown are what the querent is attracting to himself or herself.

The 6♥R, coming up as the first card of a line and having no immediate obvious meaning can signify that the situation represented by the cards following it will happen unexpectedly and will be completely new. Coming up in the middle of a sequence and having no specific meaning it can highlight the duration of the situation into the future.
The 8♥ coming at the end of a row of cards or of a sequence shows that things will go as the querent hopes. If the cards preceding it are negative, it shows that there will be cause for hope nonetheless. If it comes up reversed, it shows situations going up in smoke.

The 10♥ coming up in the middle of positive or negative cards highlights their duration over time.

The 2♣ coming up at the end of a sequence shows divine intervention, protection, liberation from hardships.

The 3♣ coming up after difficult cards shows a change of direction in the querent’s life, usually for the better.

The 3♣R coming up in the middle of a sequence and followed by positive cards show the end of negative cycles and the end of hardships in general.

The 5♣ coming up at the end or a sequence shows a stroke of luck that will change the querent’s life in the field asked about.

The 6♣ coming up at the beginning of a sequence without apparent reason shows very quick events.

The 7♣ ending a negative sequence signifies a light at the end of the tunnel, especially when followed by positive cards.

The 8♣R coming up in the middle of a sequence without reason can signify things not going as the querent expects, for better or ill.

The A♦ coming up without reason at the beginning of a sequence can show dynamic change, new impulses, etc.

The 3♦R (the Gift) coming up at the end of a difficult sequence signifies the slow resolution of hardships. This is also true when it comes in the middle, but then you need to pay attention to the cards afterward.

The 4♦R coming up at the end of a negative sequence shows relief and positivity.

The 8♦ (the Handmaid) coming up for no reason at the beginning of a sequence can show that the sequence represents a new phase or evolution in the querent’s life. Coming up for no reason at the end, it shows that the querent evolves away toward a new phase.

The 10♦ coming up at the end of a sequence which seems promising steals the positivity away (but be careful, if it is a long, extremely positive sequence, the Thief alone is not strong enough to negate it). The 10♦R coming up at the end or toward the end of a negative sequence shows that there is nothing left to do. It’s over.

The J♦ coming up at the beginning of a series for no reason announces quick developments.

The A♠R coming up in the middle of a sequence and followed by positive cards shows the end of sorrow.

The 2♠U/R coming up at the end of a negative sequence shows the waning of the matter, more or less sharply depending on whether the card is upright or reversed.

The 4♠R coming up in the middle of a sequence and followed by positive cards shows the end of a period of standstill and blockage. Followed by negative cards shows the beginning or duration of the standstill.

The 5♠ coming up in the middle of a sequence and followed by positive cards shows a difficult but positive change. If followed by negative cards, it’s difficult and negative.

The 8♠R coming up in the middle of a sequence and followed by positive cards shows the end of a period of crisis.

The 9♠R coming up in the middle of a sequence and followed by positive cards signifies liberation and unblocking. Followed by negative cards it signifies the beginning of blockage.
