And for the Snarts, those situations can involve the decision to kill your own father.
Lisa cant quite understand why.
What makes Lewis an even more vile character than the usual Central City fare?

Leonard essentially raised Lisa and, understandably, hates their father.
So she wants to save him, and Team Flash is willing to do what they can.
(Okay, nothingsthatfast.)
And a quick scan of Lisas head confirms it.
Oh and did they mention the bomb will explode if its exposed to air?
This is going to be a tough one.
To keep tabs on Snart, Barry goes undercover as an old associate of Leonards named Sam.
(Their former tech guy sadly lost his cool.
And his head.)
For all of Barrys hard work, Lewis shoots him.
NEXT: One father does wrong by his daughter while another tries to do right by his.
(Lewis may hate his sons cold gun, but it comes in handy against a laser-defense system.)
But Barry soon gets the word that Ciscos plan worked and the bomb has been removed.
He passes along the good news to Leonard, who kills his father on the spot.
(He broke my sisters heart.
Only fair I break his, Leonard gives as his reasoning.)
(Tomorrow, of course, being slang for the vague, midseason premiere date forLegends of Tomorrow.)
Cisco isnt the only one facing a potential romance, though.
First red, then blue, his fiery body collapses once again, and that can only mean trouble.
Iris mother, and his former wife, Francine, has reappeared and desperately wants to see Iris.
See, Joe had lied about Francines death long ago.
She was a drug addict who, after checking into rehab, ran away.
Francine isnt the only returning face looming over our beloved heroes, though.
